Getting System Time From SQL Server

I'm using an Access MDB as a front end to a SQL 7 database. When I place
the 
system time in a field in Access, it used the user's clock. I'd like to
use 
the SQL Server system time, so that the times will be synchronized. I 
suppose I can just do a pass-through query with "select getdate()." But I 
was wondering if there was some built-in method, either in Access or SQL 
Server. I'm concerned about the overhead of running a pass-through query 
every time I need the current time.

Thanks.
