First off, I have never started a thread so I hope I'm doing this right. Let me know if this is done properly. I am a big fan of the Apollo Lunar Surface Journal. It give the ground elapsed time for each flight. That lead me to wonder what clock time a given event happened. For the computer literate out there in FReeper land, is there a program available where you plug in a given ground elapsed time and it converts to clock time? Or, the launch and return times and dates is plugged in and the elapsed time could be calculated from those boundaries. I appreciate any help if such a program exists. Thanks in advance.
Go to http://www.timeanddate.com. Enter the time and date of the launch, then just add the elapsed time to it to get the ground time at that point.
Are you logged in? :)
Are you trying to answer queries like “What is 4:13:24:28 Apollo 11 Ground Elapsed Time in EDT?”
Actually, NCC-1701-C was the most gallant of the Enterprise class.
Something like a Unix command that spits out a local time, given the mission, ground elapsed time, and timezone (likely defaulted to your computer’s clock)?
Exactly! That’s what I’m after.
I believe I am. But you can’t be sure of anything theses days.
It takes a bit of poking around, but I just use Excel for things like that.
You probably want Google Docs (free) or Excel ($$$) or Libre Office (free). You will need to investigate the date/time functions available on your chosen platform. Then it will come down to a sheet mapping missions to launch dates and a sheet with interesting events and ground times and a column with an expression that finds the corresponding launch date and does the math to get the corresponding local time.
I don’t have a conversion such as your asking. But I’m wondering to which clock are you referring - houston, orbiter, lunar module?
Each had a clock and each would have a variance to the other depending on their relative motion over time.
When you say ground time are you referring to houston or the lunar module?
(Is there a translation button for this thread?)
Time of Day is relative to one's location on the surface of the planet; elapsed time is time compared to a fixed reference regardless of location.
What I’m after is, Houston central standard or central daylight time as it converts to mission elapsed time. For instance, when the crew of Apollo 8 started reading Genisis at, say, MET 75:23:19, what did that translate to in Houston central standard time. I admit this seems a bit tricky tack but it’s something I’ve had a fascination with since following the space program.
Thanks for the info. I’ll check out all three.
You beat me to it.....LOL!
