8.3.7.4 Daylight Saving Time (DST)
Setting of the changeover times for summer/winter time in the Sync Source (here Module
8024GPS).
This input is used to define the point of time at which the changeover to Daylight Saving Time
or winter time occurs during the course of the year. The hour, day of the week, week of the
month and month at which the Daylight Saving Time begins and ends are determined.
So the exact times are automatically calculated for the running year.
After the turn of the year the changeover times for summer/winter time are
automatically
recalculated, without any user intervention.
