That's for you to decide.  It controls how long clients may continue to see
old records after you've made a change.

If you generally know ahead of time that you're going to be making a
change, you can set the TTL to 1 day.  At least a day before you make the
change, lower it to an hour, so that the old value won't stick around long
after the change.  Once you're happy with the new value, restore the TTL
back to 1 day.

If you don't put a suffix like H (for hours), D (for days), etc. then it's
seconds.  3600 seconds is 1 hour.
