Bug #9794: DateTime.strptime() doesn't work correctly for '%s %z'
https://bugs.ruby-lang.org/issues/9794#change-46472

* Author: Felipe Contreras
* Status: Rejected
* Priority: Low

* ruby -v: 2.1.1p76
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
Time.strptime() works correctly:

    Time.strptime('0 +0100', '%s %z').strftime('%s %z')
    => "0 +0100"

But DateTime.strptime() doesn't:

    DateTime.strptime('0 +0100', '%s %z').strftime('%s %z')
    => "0 +0000"

In Rubinious it does work correctly:

    DateTime.strptime('0 +0100', '%s %z').strftime('%s %z')
    => "0 +0100"

This make the RubySL date space fail:

    DateTime#strptime parses seconds and timezone correctly FAILED
    Expected "1970-01-01T00:00:00+00:00"
     to equal "1970-01-01T01:00:00+01:00"

In addition, both C and perl preserver the offset correctly when doing '%s %z'.

So it's very clear DateTime.strptime() has to be fixed.

Patch attached.
