DateTime class
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.

Properties
- day ↔ int
-
Required. Day of month. Must be from 1 to 31 and valid for the year and
month.
getter/setter pair
- eventPlugin → EventPlugin?
-
Subclasses can override this getter to be notified of changes
to protobuf fields.
no setterinherited
- hashCode → int
-
Calculates a hash code based on the contents of the protobuf.
no setterinherited
- hours ↔ int
-
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.

.no setterinherited - minutes ↔ int
-
Required. Minutes of hour of day. Must be from 0 to 59.
getter/setter pair
- month ↔ int
-
Required. Month of year. Must be from 1 to 12.
getter/setter pair
- nanos ↔ int
-
Required. Fractions of seconds in nanoseconds. Must be from 0 to

getter/setter pair
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- seconds ↔ int
-
Required. Seconds of minutes of the time. Must normally be from 0 to 59. An
API may allow the value 60 if it allows leap-seconds.
getter/setter pair
- timeZone ↔ TimeZone
-
Time zone.
getter/setter pair
- unknownFields → UnknownFieldSet
-
no setterinherited
- utcOffset ↔ Duration
-
UTC offset. Must be whole seconds, between -18 hours and +18 hours.
For example, a UTC offset of -4:00 would be represented as
{ seconds: -14400 }.
getter/setter pair
- year ↔ int
-
Optional. Year of date. Must be from 1 to 9999, or 0 if specifying a
datetime without a year.
