What do Cellphones Talk About?

When the batteries were live, my cellphone signal detector pen would
light up at least once an hour when sitting near my cellphone. I
always assumed that useful information was being exchanged with the
nearest cell tower.

But Sunday (first morning after daylight time change in USA), I looked
at my phone and it was still an hour off. It wasn't until I made a web
connection by asking it to check my account balance that the clock
finally reset to correct time.

So what the heck are all those little talks with the cell tower about if
they don't even exchange the time of day while they are at it? (My
definition of "useful" must be different than my cellphone's).
