As a possible aid to others in converting to and from decimal day-of-year epoch dates (which has caused me some problems for over four years now), I've put online a couple of crude conversion table pages I made. For converting ordinary date to and from day-of-year: http://wwwvms.utexas.edu/~ecannon/day-date.htm and for converting hour:minute (HH:MM) to and from decimal fraction of day: http://wwwvms.utexas.edu/~ecannon/timeofday.htm Converting local to UTC date and time is a function of time zone and standard versus daylight saving time, and the trickiest thing for me has been to think "Tonight local time is tomorrow UTC!" I've ended up this year doing all of my predictions in UTC and setting my wristwatch to UTC, thus making both conform to WWV. I'm just ignoring any little problems due to having my wristwatch set to UTC! For Jim Cook, here's a page that may include a useful Mac calendar conversion program: http://allmacintosh.xs4all.be/tangerine/calclokmac.html Ed Cannon - ecannon@mail.utexas.edu - Austin, Texas, USA ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/seesat/seesatindex.html
