/**
* Formats the date of a Timestamp object according to the given format:
* This function assumes that the timestamp is local and it converts it
* to GMT before formatting.
*
* (compatible with PHP):<ul>
* <li>%a abbreviated weekday</li>
* <li>%A complete weekday</li>
* <li>%b abbreviated month</li>
* <li>%B long month</li>
* <li>%d day of the month, 2 digits with leading zero</li>
* <li>%j day of the month, numeric (without leading zero)</li>
* <li>%H hours, in 24-h format</li>
* <li>%I hours, in 12-h format (without leading zero)</li>
* <li>%p returns 'am' or 'pm'</li>
* <li>%P returns 'AM' or 'PM'</li>
* <li>%M minutes</li>
* <li>%m month number, from 00 to 12</li>
* <li>%S seconds</li>
* <li>%y 2-digit year representation</li>
* <li>%Y 4-digit year representation</li>
* <li>%O Difference to Greenwich time (GMT) in hours (Will always be +0000)</li>
* <li>%% the '%' character
* </ul>
* (these have been added by myself and are therefore incompatible with php)<ul>
* <li>%T "_day_ of _month_", where the day is in ordinal form and 'month' is the name of the month</li>
* <li>%D cardinal representation of the day</li>
* </ul>
