st: Time without date

["mai mai" <mai7777@gmail.com>]

Hi,
I have a variable that is %tc, eg: (02jan2005 10:13:43) how can make
this variable composed of time only without the date. I don't want it
to include the standard date of 1960. I am doing this because I need
to average across time of many days second by second.

Thanks!
