public sealed class DateTime : IMessage<DateTime>, IEquatable<DateTime>, IDeepCloneable<DateTime>, IBufferMessage, IMessage
Represents civil time (or occasionally physical time).
This type can represent a civil time in one of a few possible ways:
When utc_offset is set and time_zone is unset: a civil time on a calendar
day with a particular offset from UTC.
When time_zone is set and utc_offset is unset: a civil time on a calendar
day in a particular time zone.
When neither time_zone nor utc_offset is set: a civil time on a calendar
day in local time.
The date is relative to the Proleptic Gregorian Calendar.
If year is 0, the DateTime is considered not to have a specific year. month
and day must have valid, non-zero values.
This type may also be used to represent a physical time if all the date and
time fields are set and either case of the time_offset oneof is set.
Consider using Timestamp message for physical time instead. If your use
case also would like to store the user's timezone, that can be done in
another field.
This type is more flexible than some applications may want. Make sure to
document and validate your application's limitations.
Required. Hours of day in 24 hour format. Should be from 0 to 23. An API
may choose to allow the value "24:00:00" for scenarios like business
closing time.
