This is a problem with your computer clock. It thinks that it's later than it is, so it's expiring your HITs. Try syncing your computer time with the time.com servers or whoever does that.
Know what? I actually set my clock ahead a few minutes and was able to duplicate this effect. Nice find. I wonder if setting your clock back 5 or 10 minutes will let you force a longer deadline...
Great find HappyFish. I checked it right now and that is indeed the case. My clock was 5 minutes slow and when I synchronised, the HIT timer suddenly jumped by 5 minutes. But I think the server side timer does not depend on our computer clock. The time left for the HITs in the "HITs Assigned To You" shows the server side timer.
Set your clock ahead 10 minutes and you'll see that the timer does, for some reason, depend on your local computer clock.
Yeah, now I know why the HIT timer behaved erratically all the time. Sometimes it won't start, stays at 00:00, and sometimes it starts at around 3 minutes or 4 minutes. It was all due to my PC's time setting, damn.
Because this si reality that when any company produce any thing new in the market then the expiry date is fixed of this product from the manufacturing date so this is must be expire of every thing i think here is no any thing which have no expiry date mentioned or not expired whole life....
