The date command has a parameter with which you can specify the format of the
output.  The following three commands will output the hours, minutes, and
seconds respectively:
date +%H
date +%M
date +%S

Of course, setting them separately can result in skew (suppose the hour
changes between the time you set hours and minutes).  You can get output
of the form HH MM SS with the following command.
date +"%H %M %S"
and then cut it up to get the pieces you want.  

See the manual page for date(1) for the complete description of
formatting from date.
