Here are two approaches:
1) Make sure that every record in the log file includes a
timestamp. Parse all lines, locate the first timestamp that is
>= (CT - 1 hour), using everything after that line.
2) Rename the log file every hour so that you start 24 separate
logs each day, and you know that each log contains information only from a
specific hour of the day.
The first approch is more flexible, the second may be easier.
