The decimal format is not a common one but the best place to start
are the time and datetime (and calendar modules for leap years)
in the standard library. They will make writing your own
converter easier.

For time handling the time modsule includes the strptime/strftime
functions which can read/write string representations of times.

strptime/strftime can do that for you. You might find the
datetime module versions of the functions more convenient
for dates.
