Re: [tlug] Run rsync based on time difference between local file and server file

Therefore, if your machines are quite correctly time-synced, it will

I know my explanation was somewhat lacking in clarity.

Let's say I spend the day working at my office. Before I leave my office, the last thing I do with my office machine is back up to the server, going upward with an array of rsync scripts. (Of course, this only covers the files that are in common on both systems--mostly work data, app data, and mail. I know not to rsync machine-specific settings files.)
Then, when I get home, if I'm going to do a little bit more work 
that evening, I run a downward array of rsync scripts to my local 
machine. I do it this way so that I don't have to always carry a USB 
stick or drive back and forth. (Rsync seems to trash my flash drives 
for some reason anyhow)
No problem with the server solution. But sometimes if I space out, I 
begin working at my home machine, having forgotten to do the 
downward rsync, which can create some minor headaches.
But I wouldn't want to solve this by having the download scripts run 
automatically at every startup, because I start up the machine many 
other occasions besides the times when I just get home from work. 
This would be a waste of time. and some newer files that I have 
created might be deleted inadvertently.
So I was thinking I could create a short script that runs at startup 
that would test as to whether a download (or an upload) is called for.
But I forget about the UTC issue--that's a good point.

Well, this is not a big deal--just me becoming lazier and lazier I suppose...
