Hal, That's good stuff. Sadly, I've got to convert UTC to your local time to interpret the results, so I haven't done it. Tom's MJD will be even worse.
Bill, If you know C, see mjd_code.c under www.leapsecond.com/tools/. Otherwise, if you use Excel it's even easier -- just subtract the magic number 15018 from a MJD value and you get date/time in Excel format. Dealing with timezones is easy too; subtract the fraction N/24 where N is 4,5,6,7,8 here in the US. But let's keep everything in UTC since the grid crosses timezones (doesn't it?). A note about: #define MJD_TO_EXCEL(n) ( (n) - 15018 ) The reason this works is that MJD has an origin of 17-Nov-1858 and Excel uses an origin of (well, sort of) 0-Jan-1900. There are 15,018 days between those time-scales. /tvb _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
