RTCLK.PERIODE_INFO

(CAA_RealTimeClock.library)

sName

STRING(32)

Name of the time zone

stDate

RTCLK.SYSTEMTIME

Switch time

iBias    

INT

Additional offset in minutes

sName defines the name of the standard or the summer time time zone. (It is of no importance for calculations and may be left empty)

stDate defines the switch times of the time zones in local time.

iBias defines the additional offset for the respective time zone. Depending on the time zone, this value must be added to RTCLK.TIME_ZONE_INFO iBias. In most time zones iBias = 0 for the standard time and iBias = 60 for the summer time.

The summer time in Germany, Poland, Austria, Switzerland and Italy is the Central European Summer Time (CEST) which is the same as UTC plus two hours (120 min). As a result iBias = 60 for summer time.
