So if you have 2313ms coming in, we can do (pseudocode) ms_in = 2313; put_dt_ms = ms_in%1000; put_dt = SEC_TO_TIME((ms_in-put_dt_ms)/1000); -Joe @Jerry

The next issue is once you have done your math comparisons, how do you convert the value back into Time and MSec fields in order to insert them back into the table?

So How you get the microseconds? There is now solution other than the UDF posted the in the bug thread.

Are you running a counter? ok but then how the heck are you getting the micromilli secs in your columns? Are you running a counter?
