last “day” of the week (last Sunday, 3rd last Tuesday etc).

 

 

 

 

• Daylight savings is in minutes. If preceded by a (-), then subtract the number of

 

 

 

 

minutes.

“04,01,7,02,00;10,-1,7,02,00;60”.

 

 

 

 

Example: US/Canada, where daylight savings is applicable:

 

 

 

 

04,01,7,02,00;10,-1,7,02,00;60
