It seems that 1 was not a magic value as I thought, but a coincidence.

Instead of applying the adjustment to processes with a start time of 1,
apply it to all processes with a start time of less than 3600.

None of this would be necessary if the start times were recorded in ticks
instead of seconds and microseconds.
