[#absl-FromDateTime]
= xref:absl.adoc[absl]::FromDateTime
:relfileprefix: ../
:mrdocs:

A convenience wrapper for `absl::ConvertDateTime()` that simply returns the "pre" `absl::Time`. That is, the unique result, or the instant that is correct using the pre‐transition offset (as if the transition never happened).

== Synopsis

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

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
[[deprecated("Use `absl::FromCivil(CivilSecond, TimeZone)`.")]]
xref:absl/Time.adoc[Time]
FromDateTime(
    int64_t year,
    int mon,
    int day,
    int hour,
    int min,
    int sec,
    xref:absl/TimeZone.adoc[TimeZone] tz);

[WARNING]
====
https://en.cppreference.com/cpp/language/attributes/deprecated[Deprecated^]: Use `absl::FromCivil(CivilSecond, TimeZone)`.. Use of this entity is allowed but discouraged.
====
== Description

Example:

absl::Time t = absl::FromDateTime(2017, 9, 26, 9, 30, 0, lax); // t = 2017‐09‐26 09:30:00 ‐0700

Deprecated. Use `absl::FromCivil(CivilSecond, TimeZone)`. Note that the behavior of `FromCivil()` differs from `FromDateTime()` for skipped civil times. If you care about that see `absl::TimeZone::At(absl::CivilSecond)`.

== Return Value

The "pre" absolute time for the given civil time in `tz`.
