EE 2.6 Supports Relative Dates, Easier DST
EE 2.6 has some improvements with how it handles dates and time.
First, there’s no more messing with choosing whether or not you’re observing Daylight Savings Time. EllisLab says:
With the new PHP version requirements for ExpressionEngine, we were able to take advantage of more modern date handling techniques to eliminate the DST setting all together. All you will have to do is choose your timezone and we’ll take care of the rest.
Because of the new PHP version requirement we also get an enhancements in the Date field that allows relative dates to be used. Things like: “noon tomorrow” or “last day of january.”
