I recently upgraded to 2.8, and noticed that one option change was automatic Daylight Saving Time (DST) support.
However, my Administration -> Settings -> General still shows the 2.7x Time Zone setting:
hoursUTC time is 2:10 pm UTC -5 is 9:10 am
Unfortunately, you have to manually update this for Daylight Savings Time. Lame, we know, but will be fixed in the future.
Any idea why I'm not seeing the 2.8 option/automatic DST support functionality?
