Re: seconds since 1601

That's a curious date for basing dates - the iSeries can use something called a Lillian date - and the CEESECS API can convert a timestamp to seconds since 00:00:00 14 October 1582.
The Lillian date is related to the Gregorian calendar, IIRC - you could do a google on it if interested. Anyway, it is for real.
There is another API that converts seconds since that date to a character date string - CEESECM - and another that converts to integers - CEESECI - separate integers for year, month, etc.
I think you could figure out the number of seconds that the MS starting date comes after the above starting date, add that amount to whatever value they give you, then use one of the above APIs to convert.
BTW, there is a feedback code parameter - make sure to always include it - it is called omissible, but that does not mean it is optional - it is 12 bytes long - just always include it - it can be a character variable of length 12. If you don't pass it, you have to pass a NULL pointer - good luck doing that in RPG!!
Scott Klement has a lot of good info on these APIs - check the archives here or find his website.

I am doing some work reading Active Directory LDAP data from an RPG

elected to not show date/time stamps in any rational fashion. The
date/time stamp is in seconds since 00:00:00 January 1 1601 like
127122881993040000. Anyone know how to translate the number of seconds
elapsed since 00:00:00, January 1, 1601, to a date and time?
