PHP Style Format Characters with timezone identifier support

Extends support for PHP Style Format Characters including the "e" format character which will display the timezone identifier. The timezone offset is calculated for client-side timestamps as "UTC", "UTC+1", "UTC-6"; whereas it will have to be passed in for server generated timestamps by using the "timezone" parameter and passing a string value such as "UTC", "UTC+1" (or "EST", "CET" or even "America\Los Angeles" though it may occupy quite a bit of space in the clock).
With this release the "timeFormat" parameter is finally actually "timeFormat", and not "hourFormat"!
