source: trunk/include/calendar_weekly.class.php @ 4966

Last change on this file since 4966 was 4966, checked in by plg, 14 years ago

merge r4965 from branch 2.0 to trunk

bug 1047 fixed: avoid warnings when the creation date is 0000-00-00 (which
happens when date_creation comes from corrupted EXIF)

bug 859 fixed: at display time only. Piwigo still inserts wrong date in the
database, to be fixed later.
