Yep.
IF both are recorded and 'full date' VB routines are used. Unfortunately
that 'if' is often not taken into consideration. Any routine that is
expected to work pass midnight should be tested for 'midnight' - if OK, then
fine, no additional code is needed.
The programmer that doesn't validate for midnight for his particular timer
does so at his (or rather his client's) perl.
