- MFH: Fixed bug #45038 (Crash when using DateTimeZone object returned by

Kill unused vars

- MFH: Added support for using ISO 8601 time intervals to define a DatePeriod
iterator.

with the DatePeriod iterator.

- MFH: Fixed an issue in date() where a : was printed for the O modifier after
a P modifier was used.

- MFH: Added DateInterval::createFromDateString() that creates an interval
from the relative parts of a date/time string.
- MFH: Fixed an issue where special relative bits were not applied.

- MFH: Rearranged some structures to allow for more powerfull period/intervals.

- MFH: Include the starting date by default in the iterator output, but add an
option to disable this behavior.

- MFH: Added the DatePeriod class/iterator that iterates over a date time
object for a specific number of iterators and applies a DateInterval each
time.
@DOC: More will follow though

- Added new date/time functionality:
. support for diffing date/times through date_diff() / DateTime::diff().
. added DateInterval class to represent the difference between two date/times
