phpDateTime: Manipulating dates, times, time intervals

This package consists of several classes for manipulating dates, times and time intervals.

There is a class for manipulating a date, another for manipulating times (not only time of day, this can also be 156:45:10 or 3 Weeks), another to manipulate a date with time of day and another to manipulate timespans.

It supports multiple data and time representation formats (ISO, DIN, AMI, UK, MySQL, U-TSTMP), so it can be used to convert data and time values between the supported formats.

This classes are not bound the the UNIX-Timestamp, so it can easily handle dates like 4.September of 1780 or 23.120
