[php-maint] Bug#803305: php5: timezone "incorrectly" guessed from system
jaap at jaapeldering.nl

I ran into a somewhat special-case bug with the Debian patch that guesses the
timezone from the system default.
The system timezone is set to "Europe/London" in /etc/timezone, while php.ini
date.timezone is unset. In this case (after the recent change from DST to normal
time) the PHP function date_default_timezone_get() reports the timezone as UTC.
Although this is equivalent outside daylight saving time, it is not during DST,
which leads to wrong conversions between date/time strings and Unix timestamps.
I would suggest that the timezone be directly read from /etc/timezone before
using php_localtime_r(), which I assume has to infer the timezone from an
offset from UTC only.
