You should see years.  Click on the year then month, then date.  You may be able to limit it further by changing the "range" parameter, but I don't know what it specifies.
I'm only guessing, but there may be a start and finish or end parameter that can be specified to narrow the time span, but it looks like the default is a single date.
Raw packets on Findu can be UTC time stamped by adding a parameter "&time=1" to the URL and I think it may also have some start and end, or finish parameters...

I served during the cold war, so you can continue to be served a cold one.

When I drove around Crater lake I was able, quite some time later, to isolate the circuit on aprs.fi, but don't recall if it was only by date, or if clock-time limits were possible.

Subject: [aprssig] Track Playback?

Is there a way to play back an APRS track, or at least isolate a track for a
given day. 

I just got a visit from the local Sheriff.  Apparently, someone in my
neighborhood is accusing me of running her off the road into a mailbox at
about 1900 EDT (2300 UTC) last night (14 Sep).  The problem is, my truck was
parked in the driveway from about 1607 EDT until about 1800 EDT, at which
point I moved it out of the way so my wife could get by and re-parked it -
there was one beacon at about 1800 EDT and that was it until this morning.

I've pulled the raw packets from ARPS.FI, but the track is pretty much
useless since it was pretty much duplicated today.  The raw packets show the
times of the beacons, but nothing like that.

At this point, the Sheriff is just making a report and it's a case of
he-said/she-said... unless she takes it to civil court.  If that's the case,
I would like to have my ducks in a row ahead of time.  (I'm already getting
statements from the neighbors.)

Any ideas?

Thanks es 73,
