Date/Time: Use PHP `DateTime` class API in `current_time()`. 

Only use the legacy WP timestamp approach (a sum of timestamp and timezone offset) for `timestamp` and `U` formats without the `$gmt` flag.

Otherwise, make sure the function returns correct local time for any format.

Props Rarst, jdgrimes.
