As mentioned in the forum:

We should add a DST setting.

Could we build in some DST rules and execute them once a day in auto.php to see if we're on DST yet?

That'd be nice, except I believe that DST is complex... as in it's hard to know what it'll be from year to year. My understanding is that some countries don't even use the same every year but decide what the dates are on a per-year basis.

A few snippets from the web:

"date('I') works out whether DST is enabled on the server or not. Since my timezone is GMT, if DST is enabled, I just add an hour."

---

"If you want to use PHP's native time handling functionality (it's very good) in PHP4, you can also do:

CODE
putenv( "TZ=Europe/London" );"

This should have been fixed by changes released in 3.60. Marking fixed until I hear otherwise.
