public struct Duration : IEquatable<Duration>, IComparable<Duration>, IComparable, IXmlSerializable, IFormattable, ISerializableRemarks
A duration is a length of time defined by an integral number of nanoseconds. Although durations are usually used with a positive number of nanoseconds, negative durations are valid, and may occur naturally when e.g. subtracting a later Instant from an earlier one.
A duration represents a fixed length of elapsed time along the time line that occupies the same amount of time regardless of when it is applied. In contrast, Period represents a period of time in calendrical terms (years, months, days, and so on) that may vary in elapsed time when applied.
In general, use Duration to represent durations applied to global types like Instant
and ZonedDateTime; use Period to represent a period applied to local types like
LocalDateTime.
The range of valid values of a Duration is greater than the span of time supported by Noda Time - so for
example, subtracting one Instant from another will always give a valid Duration. The range
is also greater than that of TimeSpan (MinValue ticks to MaxValue ticks).
See the user guide for more details of the exact range, but it is not expected that this will ever be exceeded in normal code.
Various operations accept or return a Double, in-keeping with durations often being natural lengths
of time which are imprecisely measured anyway. The implementation of these operations should never result in a not-a-number
or infinite value, nor do any operations accept not-a-number or infinite values. Additionally, operations involving
Double have initially been implemented fairly naïvely; it's possible that future releases will improve the accuracy
or performance (or both) of various operations.
Properties
BclCompatibleTicks
Declaration
public long BclCompatibleTicks { get; }Property Value
| Type | Description |
|---|---|
| Int64 | The total number of ticks in the duration. |
Remarks
Within the constraints specified below, this property is intended to be equivalent to Ticks.
If the number of nanoseconds in a duration is not a whole number of ticks, it is truncated towards zero. For example, durations in the range [-99ns, 99ns] would all count as 0 ticks.
Although this method can overflow, it will only do so in very exceptional cases, with durations with a magnitude of more than 29000 Gregorian years or so.
Exceptions
| Type | Condition |
|---|---|
| OverflowException | The number of ticks cannot be represented a signed 64-bit integer. |

TotalDays
Declaration
public double TotalDays { get; }Property Value
| Type | Description |
|---|---|
| Double | The total number of days in this duration. |
Remarks
Duration equivalent of TotalDays.
It represents the complete duration in days, rather than only the whole number of
days. For example, for a duration of 36 hours, this property would return 1.5.
TotalHours
Declaration
public double TotalHours { get; }Property Value
| Type | Description |
|---|---|
| Double | The total number of hours in this duration. |
Remarks
Duration equivalent of TotalHours.
Unlike Hours, it represents the complete duration in hours rather than the
whole number of hours as part of the day. So for a duration
of 1 day, 2 hours and 30 minutes, the Hours property will return 2, but TotalHours
will return 26.5.
TotalMilliseconds
Declaration
public double TotalMilliseconds { get; }Property Value
| Type | Description |
|---|---|
| Double | The total number of milliseconds in this duration. |
Remarks
Duration equivalent of TotalMilliseconds.
Unlike Milliseconds, it represents the complete duration in seconds rather than
the whole number of seconds within the minute. So for a duration
of 10 minutes, 20 seconds and 250 milliseconds, the Seconds property will return 20, but TotalSeconds
will return 620.25.
TotalMinutes
Declaration
public double TotalMinutes { get; }Property Value
| Type | Description |
|---|---|
| Double | The total number of minutes in this duration. |
Remarks
Duration equivalent of TotalMinutes.
Unlike Minutes, it represents the complete duration in minutes rather than
the whole number of minutes within the hour. So for a duration
of 2 hours, 30 minutes and 45 seconds, the Minutes property will return 30, but TotalMinutes
will return 150.75.
TotalNanoseconds
Declaration
public double TotalNanoseconds { get; }Property Value
| Type | Description |
|---|---|
| Double | This duration as a number of nanoseconds, represented as a Double. |
Remarks
Double type. In other works, Duration.FromNanoseconds(duration.TotalNanoseconds)
is not guaranteed to round-trip. To guarantee precision and round-tripping,
use ToBigIntegerNanoseconds() and FromNanoseconds(BigInteger).
TotalSeconds
Declaration
public double TotalSeconds { get; }Property Value
| Type | Description |
|---|---|
| Double | The total number of seconds in this duration. |
Remarks
Duration equivalent of TotalSeconds.
Unlike Seconds, it represents the complete duration in seconds rather than
the whole number of seconds within the minute. So for a duration
of 10 minutes, 20 seconds and 250 milliseconds, the Seconds property will return 20, but TotalSeconds
will return 620.25.
TotalTicks
Declaration
public double TotalTicks { get; }Property Value
| Type | Description |
|---|---|
| Double | The total number of ticks in this duration. |
Remarks
Duration equivalent of Ticks,
except represented as double-precision floating point number instead of a 64-bit integer. This
is because Duration has a precision of nanoseconds, and also because the range
of 64-bit integers doesn't cover the number of possible ticks in a Duration. (The
latter is only an issue in durations outside the range of TimeSpan - in other words,
with magnitudes of over 29,000 years.)

A duration is a length of time defined by an integral number of nanoseconds. Although durations are usually used with a positive number of nanoseconds, negative durations are valid, and may occur naturally when e.g. subtracting a later Instant from an earlier one.
A duration represents a fixed length of elapsed time along the time line that occupies the same amount of time regardless of when it is applied. In contrast, Period represents a period of time in calendrical terms (years, months, days, and so on) that may vary in elapsed time when applied.
In general, use Duration to represent durations applied to global types like Instant
and ZonedDateTime; use Period to represent a period applied to local types like
LocalDateTime.
The range of valid values of a Duration is greater than the span of time supported by Noda Time - so for
example, subtracting one Instant from another will always give a valid Duration. The range
is also greater than that of TimeSpan (MinValue ticks to MaxValue ticks).
See the user guide for more details of the exact range, but it is not expected that this will ever be exceeded in normal code.
Various operations accept or return a Double, in-keeping with durations often being natural lengths
of time which are imprecisely measured anyway. The implementation of these operations should never result in a not-a-number
or infinite value, nor do any operations accept not-a-number or infinite values. Additionally, operations involving
Double have initially been implemented fairly naïvely; it's possible that future releases will improve the accuracy
or performance (or both) of various operations.

A duration is a length of time defined by an integral number of nanoseconds. Although durations are usually used with a positive number of nanoseconds, negative durations are valid, and may occur naturally when e.g. subtracting a later Instant from an earlier one.
A duration represents a fixed length of elapsed time along the time line that occupies the same amount of time regardless of when it is applied. In contrast, Period represents a period of time in calendrical terms (years, months, days, and so on) that may vary in elapsed time when applied.
In general, use Duration to represent durations applied to global types like Instant
and ZonedDateTime; use Period to represent a period applied to local types like
LocalDateTime.
The range of valid values of a Duration is greater than the span of time supported by Noda Time - so for
example, subtracting one Instant from another will always give a valid Duration. The range
is also greater than that of TimeSpan (MinValue ticks to MaxValue ticks).
See the user guide for more details of the exact range, but it is not expected that this will ever be exceeded in normal code.
Various operations accept or return a Double, in-keeping with durations often being natural lengths
of time which are imprecisely measured anyway. The implementation of these operations should never result in a not-a-number
or infinite value, nor do any operations accept not-a-number or infinite values. Additionally, operations involving
Double have initially been implemented fairly naïvely; it's possible that future releases will improve the accuracy
or performance (or both) of various operations.

A duration is a length of time defined by an integral number of nanoseconds. Although durations are usually used with a positive number of nanoseconds, negative durations are valid, and may occur naturally when e.g. subtracting a later Instant from an earlier one.
A duration represents a fixed length of elapsed time along the time line that occupies the same amount of time regardless of when it is applied. In contrast, Period represents a period of time in calendrical terms (years, months, days, and so on) that may vary in elapsed time when applied.
In general, use Duration to represent durations applied to global types like Instant
and ZonedDateTime; use Period to represent a period applied to local types like
LocalDateTime.
The range of valid values of a Duration is greater than the span of time supported by Noda Time - so for
example, subtracting one Instant from another will always give a valid Duration. The range
is also greater than that of TimeSpan (MinValue ticks to MaxValue ticks).
See the user guide for more details of the exact range, but it is not expected that this will ever be exceeded in normal code.
Various operations accept or return a Double, in-keeping with durations often being natural lengths
of time which are imprecisely measured anyway. The implementation of these operations should never result in a not-a-number
or infinite value, nor do any operations accept not-a-number or infinite values. Additionally, operations involving
Double have initially been implemented fairly naïvely; it's possible that future releases will improve the accuracy
or performance (or both) of various operations.
