[Bug 1451328] Re: Timezone identifier support for PHP on Windows

 

Due to the limited development resources available to the Mahara core
team, we don't officially support or test Mahara on platforms other than
Ubuntu and Debian. That said, we are always willing to make small code
changes to accommodate running on other platforms.

Doing a quick search through the code, I see that, although we have that
prominent sanity check for %z, we actually only use %z in one place,
during Leap2a exports. So that shouldn't be causing the problem that
you're describing. I think the main problem that would cause, is that if
you do a Leap2a export & import, you'll get weird dates on, for
instance, blog entries.

Looking at the PHP docs for strftime() (
http://php.net/manual/en/function.strftime.php ), I see that %e also
doesn't work properly in Windows. We do use that in the "strftimedate"
formatting string. However, the string that displays the last login
dates on the user search page, is "strftimedatetime" in langconfig.php,
which is "%%d %%B %%Y, %%l:%%M %%p". In theory that formatting string
should work fine in Windows.

So, I'm not really sure what the fix is here.

Could you take a look in your database and see if the user's dates are
stored properly in the "usr.lastlogin" column?

Title:
  Timezone identifier support for PHP on Windows

Status in Mahara ePortfolio:
  Triaged

Bug description:
  Last login column for users search is blank (and does not sort in the
  correct order) also the warning saying 'PHP on your website host does
  not return a useful value for the timezone identifier (%z) .....' on
  the admin page is not a fix for the problem and unfortunately some of
  us are not able to change from hosting on a Windows server.

  I am wondering if Mahara is using strftime resulting in the time zone
  identifier returning 'New Zealand Standard Time' in Windows rather
  than Linux' +1200 is part of the problem.

  I have searched the forums but not found a fix.

  Server: Windows 2012 R2
  Mahara version: 15.04.0 and 1.9.4
  IIS: 8.5 (both servers) also had same problem on a WAMP environment
  PHP version: 5.5.3 and 5.5.8
  MySQL version: 5.5.40 on both servers
