Instant type supports the following patterns:
The following standard pattern is supported:
g: General format pattern. The ISO-8601 representation of this instant in UTC, using the pattern "uuuu-MM-ddTHH:mm:ss'Z'" and always using the invariant culture, with the default "start of time" and "end of time" labels. This is the default format pattern.
Instant supports all the
LocalDateTime custom patterns.
The pattern allows the culture to be specified, but always uses the ISO-8601 calendar, and always uses the UTC
time zone. The "template value" is always the Unix epoch.
