Std stands for the time zone (for example, CET for Central European Time or MET for
Middle European Time).
Offset specifies the time difference between the time zone and UTC, for example, -1 for
Central European Time. The difference is negative if the time zone is ahead of UTC. If the
time difference does not comprise full hours, the number of minutes can be added, for
example, -1:30. The TZ string ends here if you are not using a summer time.
Dst stands for the summer time zone (for example, CEST for Central European Summer
Time or MES for Middle European Summer Time).
The optional, second Offset parameter gives the offset of the summer time in respect of
UTC. An hour before normal time is assumed if no entry is made.
Date/Time define the start and end of summer time. The format for a time entry is
Mm.n.d, signifying the d-th day of the n-th week of the m-th month. Day 0 is Sunday. If
the fifth week is entered, the last day (with respect to d) of the month is meant. The
format for a time entry is hh[:mm[:ss]], in the 24-hour format.
