A better date and time API for .NET

Noda Time is an alternative date and time API for .NET. It helps you to think about your data more clearly, and express operations on that data more precisely.

Examples (see User Guide)

// Instant represents time from epoch
Instant now = SystemClock.Instance.GetCurrentInstant();

// Convert an instant to a ZonedDateTime
ZonedDateTime nowInIsoUtc = now.InUtc();

// Create a duration
Duration duration = Duration.FromMinutes(3);

// Add it to our ZonedDateTime
ZonedDateTime thenInIsoUtc = nowInIsoUtc + duration;

// Time zone support (multiple providers)
var london = DateTimeZoneProviders.Tzdb["Europe/London"];

// Time zone conversions
var localDate = new LocalDateTime(2012, 3, 27, 0, 45, 00);
var before = london.AtStrictly(localDate);
