Re^4: how to convert a timestamp to MJD (Modified Julian Date)

Again, agreed that the question was lacking. I was not aware the original post was back-modified; that explains your reply. I was led to this post in the first place after reading the pod for Time::Julian, which had a bothersome Errata that refered me to Astro::Time which uses the term Modified Julian day with only (JD-~~2500000.5~~ 2400000.5) as a definition. I got a hit for perlmonks and was reassured, but then disappointed reading the responses. I think I'll write my own code rather than use a module. Probably wont post it though.

As far as I know (by which I mean, I read the wikipedia page on Julian dates), JD-2500000.5 is the definition of MJD. In any case, see my post below if you're interested in a solution that doesn't require you to rewrite date parsing code.

I modified my prior post to correct the constant (which I won't repeat for fear of typing it wrong again). Also, for those who have trust issues with wikiped, here is another site (assuming you don't have trust issues with the US navy). http://tycho.usno.navy.mil/mjd.html Update: Of course I now see this link is an external link on the wikiped page itself.
