Regarding the discussions of Martian time, more details of the system they're using are here:
http://www.giss.nasa.gov/tools/mars24/help/notes.html It seems they've defined Martian "hours", "minutes", and "seconds" as appropriate fractions of the Martian day (which they call a "sol"). This means that there's a "Martian second" which differs from the SI second, and is defined in terms of solar cycles on Mars (and presumably would change its length over time based on any astronomical change in the rotation of Mars). So, maybe what we need is an "Earth second" also based on solar cycles (as the second always was prior to the middle of the 20th century), distinct from the scientific second based on atomic clocks? -- == Dan == Dan's Mail Format Site: http://mailformat.dan.info/ Dan's Web Tips: http://webtips.dan.info/ Dan's Domain Site: http://domains.dan.info/
