Create Unix timestamp given the time only

Question

I have a time value, in seconds, for example 4:20pm being 58800 . From this value I need to get the Unix timestamp, assuming today's date. How should I approach this?

Answer 1

start_of_day = datetime.datetime.combine(datetime.date.today(), datetime.time())
dt = start_of_day + datetime.timedelta(seconds=58800)

Like so?
