Ok done. times are now in format Y-m-d (GMT)

I added some titles. For the delay I added "Average difference between
time of probe and last sychronization". This means if I download the
lastsync file at 12:00 from your mirror and the file indicates that you
have synced at 10:00 you got a delay of 2 hours.Of course this is very
rough but should give us an idea how often you sync with the master
server (directly or indirectly). We might update the lastsync file more
often in future to get some better results. For now I would guess we
have an error of about one hour.

Thanks for your feedback btw.. This was one of the projects you do just
for fun and should never actually be used by anybody. :-)

Greetings,

Pierre
