Hi,
ASE 12 is very old and since no Eng support maybe decision made to not use datetime. However, you can certainly request feature - if you are able to create incident we can create Feature and then incident can be used for tracking purposes, etc.
If unable to create incident please provide details:
ASE version (exact with select @@version)
SDK version being used
code sample to demonstrate problem and the output from such a test
If you used TDS please provide that trace as well if possible
Cheers,
-Paul
