4 GNSS Receiver
4.1.3.15 Setup Output Time Zone
The time zone of the internal receiver can be set up. These parameters will affect the serial output lines and
the timecode (IRIG) outputs. The internal time zone of the timeserver and the time of NTP will always be UTC.
The time monitored in the main menu will be the time of the NTP.
The menu
Set Timezone
lets the user enter the names of the local time zone with daylight saving disabled
and enabled, together with the zones time offsets from UTC. These parameters are used to convert UTC to local
time, e.g. CET = UTC + 1h and CEST = UTC + 2h for central Europe. The values of daylight saving are
configurable using the Time Zone setup menu.

Beginning and ending of daylight saving may either be defined by exact dates for a single year or using an
algorithm which allows the receiver to re-compute the effective dates year by year.The figure show how to enter
parameters for the automatic mode. If the number of the year is displayed as wildcards ’****’, a day-of-week
must be specified. Then, starting from the configured date, daylight saving changes the first day which matches
the configured day-of-week. In the figure October 25th is a Saturday, so the next Sunday is October 26th.
All changeover rules for the daylight saving like "the first/the second/the second to last/the last Sunday/-
Monday etc. in the x-th month," can be described by the used format "first specified day-of-week after a defined
date".
If the number of the year is not displayed as wildcards the complete date exactly determines the day daylight
saving has to change, so the day-of-week does not need to be specified.
If no changeover in daylight saving is wanted, identical dates and times must be entered in both of the submenus
(DAYLIGHT SAV ON/OFF). After this a restart should be done.
