Time convertion

Hi!

I have to convert some date formats, and I wonder why IDL does not give
more support here. A common date/time format is the seconds since 1970,
and the systime() funtion can return the current date in this format.
Yippie! But why is there no function to convert this from/to standard
ASCII date strings, or from/to Julian date? 

I found such a thing in the Astro library, st2date, input is the
seconds-since-1970, output is year, month, day etc., and even day and
month in ASCII notation if one likes. Great. But I did not find
something yet to convert to seconds-since-1970. I could write it myself,
but I guess this already had be done some dozen times. Some big routine
with many, many keywords to convert between all those formats would be
nice :)
