In reasonably recent versions of SPSS, you can use date constants on the MISSING VALUES command(also the VALUE LABELS command), e.g.,
MISSING VALUES bdate ( '02/10/1929' ).
They must be quoted and use the format of the variable being labeled.
In the user interface, you can do this via Data>Define Variable Properties. Select the variable(s) of interest. You will see a display of the values, and you can just check the missing values box for the ones you want.
If you have too old a version, you will have to figure out the actual number behind the time value and use that on the command.

Subject: [SPSSX-L] declare missing for time data
Dear list, does anyone know how to declare time data as missing.
I have some invalid times in HH:MM format that I want to declare as
missing but have been able to figure out if it can be done.
