DateTime

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, month, or day are 0, the DateTime is considered not to have a specific year, month, or day respectively.

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.

Fields
year

int32

Optional. Year of date. Must be from 1 to 9999, or 0 if specifying a datetime without a year.
month

int32

Optional. Month of year. Must be from 1 to 12, or 0 if specifying a datetime without a month.
day

int32

Optional. Day of month. Must be from 1 to 31 and valid for the year and month, or 0 if specifying a datetime without a day.
hours

int32

Optional. Hours of day in 24 hour format. Should be from 0 to 23, defaults to 0 (midnight). An API may choose to allow the value "24:00:00" for scenarios like business closing time.
minutes

int32

Optional. Minutes of hour of day. Must be from 0 to 59, defaults to 0.
seconds

int32

Optional. Seconds of minutes of the time. Must normally be from 0 to 59, defaults to 0. An API may allow the value 60 if it allows leap-seconds.
nanos

int32

Optional. Fractions of seconds in nanoseconds. Must be from 0 to 999,999,999, defaults to 0.
Union field time_offset. Optional. Specifies either the UTC offset or the time zone of the DateTime. Choose carefully between them, considering that time zone data may change in the future (for example, a country modifies their DST start/end dates, and future DateTimes in the affected range had already been stored). If omitted, the DateTime is considered to be in local time. time_offset can be only one of the following:
utc_offset

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 }.
time_zone

TimeZone

Time zone.

Expr

Represents a textual expression in the Common Expression Language (CEL) syntax. CEL is a C-like expression language. The syntax and semantics of CEL are documented at https://github.com/google/cel-spec.

Example (Comparison):

title: "Summary size limit"
description: "Determines if a summary is less than 100 chars"
expression: "document.summary.size() < 100"

Example (Equality):

title: "Requestor is owner"
description: "Determines if requestor is the document owner"
expression: "document.owner == request.auth.claims.email"

Example (Logic):

title: "Public documents"
description: "Determine whether the document should be publicly visible"
expression: "document.type != 'private' && document.type != 'internal'"

Example (Data Manipulation):

title: "Notification string"
description: "Create a notification string with a timestamp."
expression: "'New message received at ' + string(document.create_time)"

The exact variables and functions that may be referenced within an expression are determined by the service that evaluates it. See the service documentation for additional information.

Fields
expression

string

Textual representation of an expression in Common Expression Language syntax.
title

string

Optional. Title for the expression, i.e. a short string describing its purpose. This can be used e.g. in UIs which allow to enter the expression.
description

string

Optional. Description of the expression. This is a longer text which describes the expression, e.g. when hovered over it in a UI.
location

string

Optional. String indicating the location of the expression for error reporting, e.g. a file name and a position in the file.

TimeZone

Represents a time zone from the IANA Time Zone Database.

Fields
id

string

IANA Time Zone Database time zone, e.g. "America/New_York".
version

string

Optional. IANA Time Zone Database version number, e.g. "2019a".
