Hello Everybody

I have to set the accountexpires value in our active directory.
I get the date, when a person will leave our company(25000 employees) from a SAP System.
I found this in MSDN:
The value in the AD "represents the number of 100 nanosecond intervals since January 1, 1601" !!!???

For example:
If a person leaves our company at 15th of july 2007, i want to calculate the needed value for 15.07.2007 (german date) 23:59:00
But no idear ???????????

Any help welcomed
Best regards
Albert
