Update Punic to 1.0.2
Improve toDateTime to allow timezone conversions
Deprecate getLocalDateTime, getSystemDateTime, dateTimeFormatLocal
Better docs for getTimezones
Improve getTimezoneDisplayName
Rename getTimezone to getTimezoneID, add getTimezone

Having a getTimezone that returns a \DateTimeZone instance may be handy
Add support for destination timezone to date()
Add support for destination timezone to formatCustom()
Add toDB method to format any date/time representation to an SQL date/time string
Add getOverridableNow

Let's adopt a specific method to get the current date/time or the custom request time
Use getOverridableNow instead of getLocalDateTime
Remove getSystemDateTime

Use getOverridableNow or formatCustom (or even nothing) instead of that deprecated method
Use getOverridableNow instead of toDB('now')

Just for consistency, I don't think that this makes a great difference BTW ;)
