DateTime format

[kudzu]

Its not IW because the code you are using is pure RTL, not IW code. strToDateTime is RTL.

As I explained, SA and ISAPI by default will run as different users on your system and the region settings of each user can alter the behavior of strToDateTime. This is why its always best to code the format directly and never rely on region settings for server based applications.

Likely a SP or some other change altered the region settings of the user your ISAPI runs under.
