It seems to me that this is something that date functions in SQL could do for you. You could either use DATEDIFF with 1/1/1970 (and multiply by seconds per day) to come up with 'seconds since epoch' or you could use DATEPART to dismember the date and calculate 'seconds since epoch' yourself. Either way, if you're already selecting a row from a MSSQL database, it shouldn't require any extra modules. I'm not a MSSQL guy, but this might help you.
