Hi,

Check out the C() format codes. http://star.pst.qub.ac.uk/idl/C()_Format_Code.html

IDL> PRINT, FORMAT='(C(CDI))',SYSTIME(/JULIAN)
7

If you need it stored into a variable then you can use STRING...

IDL> print, FIX(STRING(SYSTIME(/JULIAN), FORMAT='(C(CDI))'))*2
14

You have to provide the timestamp as one of IDL's julian day numbers.

Cheers,
ben
