Zend_TimeSync is able to receive internet or network time from a time
server using the NTP or SNTP protocol.
Zend_TimeSync, Zend Framework is able to act independently from
the time settings of the server where it is running.
To be independent from the actual time of the server,
works with the difference of the real time which is sent through NTP or SNTP and the
internal server's time.
Zend_TimeSync is not able to change the server's time, but it
will return a Zend_Date instance from
which the difference from the server's time can be worked with.
