Re: JULDAY 5.4 not same as 5.3?

[Don Woodraska <don.woodraska(at)lasp.colorado.edu>]

I should have included this in the original post:

IDL> print,!version
{ sparc sunos unix 5.4 Sep 25 2000      64      64}

Thanks for your response Mark.  I'll bet it must be a 64-bit-only bug.
Can anyone else verify this bug on another 64-bit machine?

Interestingly, if I don't pass the hour, minute, and second, then I get
the correct answer with version 5.4.

Thanks,
Don
