CWT Software Configuration Handbook
Element Path: <cwt><CALENDAR><standardDateRule>
This function is used to set the rule for when the automatic change from daylight saving time to standard time shall be executed. The size of the change is set with the daylightSavingOffset tag (see DaylightSavingOffset ). For details on calendar rules, see Section Calendar rules below.
| Note: You have to set the attributes for both the summertime ( daylightSavingDateRule ) and the wintertime ( standardDateRule ). The terminal will not accept only summer or winter settings because these attributes depend on each other. |
