StdOffset[Dst[Offset], Date/Time, Date/Time]
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, 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.
The Central European time zone which applies to Germany is specified as follows:
CET-1CEST-2,M3.5.0/2,M10.5.0/3
