Syntax

res = DCF77TimeZone()

Res	The target variable that is assigned with the result. The result will be: - 0: when there is no valid DCF77 data yet - 1: when in "Middle Europe Normal Time" - 2: when in "Middle Europe daylight saving Time"

In Middle Europe, daylight saving is used to make better use of the day light in the summer.

The last Sunday in March at 02:00 AM the Daylight Saving will start. All clocks are set from 2:00 to 3:00.

Your weekend, is one hour shorter then.

But the last Sunday of October is better : at 03:00 AM, the Daylight Saving will end and all clocks are set from 03:00 to 02:00.

When you have a lot of clocks in your house, you can understand why DCF77 synchronized clocks are so popular.
