IIRC the timestamps ignore time spent in GC and time spent sampling
the heap, so they measure runtime of the program only.
So if I have a server that is idle most of the time waiting for
requests, the timestamps recorded in the heap profile will not be "real
time" but program execution time?
Still, it does look a little strange. Maybe you could send us the
output of +RTS -S?
