= xref:absl.adoc[absl]::AbslParseFlag
:relfileprefix: ../
:mrdocs:

Parses the command‐line flag string representation `text` into a Time value. Time flags must be specified in a format that matches absl::RFC3339_full.

== Synopsis

Declared in `<absl/time/time.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
bool
AbslParseFlag(
    std::string_view text,
    xref:absl/Time.adoc[Time]* t,
    std::string* error);
----

== Description

For example:

‐‐start_time=2016‐01‐02T03:04:05.678+08:00

Note: A UTC offset (or 'Z' indicating a zero‐offset from UTC) is required.

Additionally, if you'd like to specify a time as a count of seconds/milliseconds/etc from the Unix epoch, use an absl::Duration flag and add that duration to absl::UnixEpoch() to get an absl::Time.

== Return Value

`true` upon successful parsing.
