NAME

gcloud topic datetimes - date/time input format supplementary help

DESCRIPTION
gcloud command line flags and filter expressions that expect date/time string values support common input formats. These formats fall into two main categories: absolute date/times and relative durations.

Absolute date/time formats
Absolute date/time input formats minimally support ISO 8601 (https://en.wikipedia.org/wiki/ISO_8601) and RFC 822 (https://www.ietf.org/rfc/rfc0822.txt) date/times. When omitted the date/time value defaults are:

    •   year, month, day - current value

    •   hour, minute, second, fractional second - 0

The supported absolute date/time input formats are listed here. ISO 8601 / RFC 3339 zulu:
    2003-09-25T10:49:41.519Z 2003-09-25T10:49:41Z
ISO 8601 numeric timezone offset:
    2003-09-25T10:49:41.5-0000 2003-09-25T10:49:41.5-03:00 2003-09-25T10:49:41.5+0300
ISO with omitted parts:
    2003-09-25T10:49:41 2003-09-25T10:49 2003-09-25T10 2003-09-25
RFC 822:
    Thu, 25 Sep 2003 10:49:41 -0300
UNIX date command, explicit timezone:
    Thu Sep 25 10:36:28 EDT 2003 2003 10:36:28 EDT 25 Sep Thu
local timezone:
    Thu Sep 25 10:36:28 2003
omitted parts (date parts default to the current date, time parts default to 0):
    Thu Sep 25 10:36:28 Thu Sep 10:36:28 Thu 10:36:28 Thu 10:36 10:36
omitted parts with different order:
    Thu Sep 25 2003 Sep 25 2003 Sep 2003 Sep 2003
ISO no separators:
    20030925T104941.5-0300 20030925T104941-0300 20030925T104941 20030925T1049 20030925T10 20030925
no T separator:
    20030925104941 200309251049
other date orderings:
    2003-09-25 2003-Sep-25 25-Sep-2003 Sep-25-2003 09-25-2003
other date separators:
    2003.Sep.25 2003/09/25 2003 Sep 25 2003 09 25

Relative duration date/time formats
Relative durations are based on ISO 8601 durations (https://en.wikipedia.org/wiki/ISO_8601#Durations). Relative durations are case-insensitive and must be prefixed with +P or -P. They denote offsets from the current time. A fully qualified duration string contains year, month, day, hour, minute, second, and fractional second parts. Each part is a number followed by a single character suffix:

    •   P - period (the duration designator)

    •   Y - year

    •   M - minute if after T or H, month otherwise

    •   D - day

    •   T - separates date parts from time parts

    •   H - hour

    •   M - minute if after T or H, month otherwise

    •   S - second (for fractional seconds, use decimal value for seconds)

At least one part must be specified. Omitted parts default to 0.
    -P1Y2M3DT4H5M6.7S +p1y2m3dT4h5m6.7s
A relative duration may be used in any context that expects a date/time string. For example:

    •   1 month ago: -p1m

    •   30 minutes from now: +pt30m

    •   2 hours and 30 minutes ago: -p2h30m
