Comment (by Otto42):

 Viper007: The city list is standardized, albeit updated every so often:
 http://en.wikipedia.org/wiki/Zoneinfo
 http://en.wikipedia.org/wiki/List_of_zoneinfo_timezones

 What's more, PHP can even produce it on demand:
 http://php.net/manual/en/function.timezone-identifiers-list.php

 When it comes to timezones and handling daylight savings time, the
 zoneinfo method is the One True Way(tm).

 However, after looking closely at 2.5's method of handling this, I believe
 this could be handled by a plugin in the right way. Essentially, I'd hook
 a filter onto the gmt_offset option, and replace it with the offset as
 calculated by the timezone functions (if they were available).
