The timer on the admin page gives incoherent results. I frequently set a "one
hour" timer by using 3600 seconds. As soon as I click the "set" button, it shows
1 hour, but then when I click away from that page, it mysteriously adds one
minute to the clock! When trying to set for longer periods, such as 3 hours or
10800 seconds, the results are wildly unpredictable, and frankly hard to use. I
just now set it for 10800 and it showed 3 hours; yet when I navigated away from
the page, it showed 3 hours 59 minutes. I had to go back and experiment, finally
setting for 8000 seconds, then when I navigated away it showed 3 hours.
Something is being inadvertenly added to, or multiplied, incorrectly.
