There are probably clever non-Python ways to do this, but if you're
using Python, getting the current local date is pretty easy using the
mydate = str(datetime.date.today())
which returns '2009-08-11' as a string. If you want the date to be
formatted differently, as in your example, you can extract and rearrange
the date components, e.g., something like...
myyear = str(datetime.date.today().year) # extract the year from the
date object, as a string
mymonth = str(datetime.date.today().month) # extract the month from
the date object, as a string
myday = str(datetime.date.today().day) # extract the day from the date
object, as a string
datestring = myyear[2:4] + mymonth.zfill(2) + myday # retain just the
last two digits of the year, and if the month is a single digit, left
pad it with a '0'
...which gives datestring a value of '090811'. I'm sure there are more
elegant ways to do this in Python, but you get the idea.
