I'm wondering if this is a bug.

My timezone and server timezone are both set to -7 in the preferences. My user timezone is also set to -7.

If I use php and mysql to check the time on the server, both php and mysql show the correct time, so there is no problem on the server.

I add a recurring event 9 times starting April 26 from 19:00 - 21:00 (2 hours).

In April, the time shows correctly, but for May forward, it shows 20:00 - 22:00. Then, in November, it goes back to showing 19:00 - 21:00.

Even more strange is if I click to edit the May event, the time shows up as 19:00 - 21:00, but viewing it shows 20:00 - 22:00. If I check the value in the database, the unix time stamp converts to the 20:00 - 22:00 so it is being stored in the DB incorrectly.

Nonetheless, the one hour difference from May - November almost coincides with daylight savings time. Clocks move forward in April and back in October. I'm wondering if there is some code buried in there that is incorrectly and automatically adjusting for Daylight Savings time? I just can't seem to find it.
