and here are some more julian seconds routines

http://www.fz-juelich.de/icg/icg1/idl_icglib/idl_source/idl_ html/dbase/download/string2js.tar.gz
http://www.fz-juelich.de/icg/icg1/idl_icglib/idl_source/idl_ html/dbase/download/js2string.tar.gz

There are many formats defined

e.g.:
; FORMAT: string to format the output:
; 'ICG' = 'Y-M-D H:M:S MS'
; 'XLS' = 'D.M.Y H:M:S'
; 'M-D'
; 'H:M'
; 'H:M:S'
; 'Y-M-D'
; 'M-D-Y'
; 'YMDHMS'

For further routines and licensing please look at
