How do I check if a date is UTC?
2 Answers
- If all you need is “now” as a UTC DateTime , just use DateTime.
- If you are working with Noda Time instants and need a DateTime , just use instant.
- If you want to validate a DateTime is in UTC, then check the kind: dateTime.Kind == DateTimeKind.Utc.
- Your data layer will probably return DateTimeKind.
