Send date/time from fortran to C

[CJason]

I am wanting to send a fortran date (what form should this be...real*8, integer*8, etc...???) into a C function, then that C function return if the input date is in Daylight Savings time or not. Any ideas on how I could pass this info back and forth from Fortran to/from C?

Thanks in advance!!

Need to know several things first

1) Which C compiler are you using (and what is the platform)
2) Which Fortran compiler are you using
3) Which version of Fortran (77, 90, 95, 2003) are you using?

Fortran 2003 has a C interface.
