Expert - Setting time zones

1.Using your own time zone

If this switch is activated, you can set a time zone in the selection box (which is specified there).
Note: All time zones that have a winter time/summer time changeover are marked with a '*'.

2.Selection of list of time zones

All the time zones entered in the "tz.dat" file are listed here. You can only always activate one time zone.

3.The "tz.dat" file

The "tz.dat" file is located in the "\dat" subdirectory of Expert. It can be processed using a normal text editor like the Windows "Editor".

The format of the entries:
Zx|Text|AAA+-yBBB+-z,Mm.w.d/HH:mm:ss,Mm.w.d/HH:mm:ss

Zx = A clear abbreviation like Z1, Z2, Z3, ...
Text = Free description text for the time zone
AAA = The official designation of the time zone (3 or character) for the standard time (=winter time). Some European time zones are, for example, CET, GMT and MSK.
An English language Internet page on this topic is available here. (External link).
+-y = Difference in hours in order to maintain UTC (Universal Time, Coordinated).
Positive entry when the set time zone lies west of the zero meridian, negative entry when it lies east of the zero meridian.
If NO deviation is desired, please enter a '+0'!
(CET = UTC+1)
Times are frequently specified in GMT (Greenwich Mean Time). The following applies: GMT = UTC.
BBB = The official designation of the time zone (3 or character) for summer time. Some European summer time zones are, for example, CEST, BST and MSD.
This and all the subsequent entries do not apply if the time zone has no summer time
+-z = Difference in hours in order to maintain UTC (Universal Time, Coordinated), added with the difference of the winter time to the summer time (usually 1 hour).
Positive entry when the set time zone lies west of the zero meridian, negative entry when it lies east of the zero meridian.
If NO deviation is desired, please enter a '+0'!
Mm = Month in which the changeover is made from winter time to summer time. Number from 1 to 12.
w = nth week in the month 'm', in which the day of the week 'd' occurs. Number from 1 to 5.
1 is always the first week in the month, 5 is always the last week in the month
d = day of the week. Number from 0 (Sunday) to 6 (Saturday).
HH = hour. Number from 00-24. Always has to be entered in 2-digit form.
The time always relates to the time that is currently valid.
mm = Minutes. Number from 00-59. Always has to be entered in 2-digit form.
ss = Seconds. Number from 00-59. Always has to be entered in 2-digit form.

The first group "Mm.w.d/HH:mm:ss" determines the time of the changeover from winter time to summer time. The point in time must be specified in winter time.
The second group "Mm.w.d/HH:mm:ss" determines the point in time of the changeover from winter time to summer time. The point in time has to be specified in summer time.

The time is optional at this point. If the time is not specified, 02:00:00 is used as the point in time.

Example: (Usual setting for Central Europe)
