[SC-Help] Average reporting time and timezones

[David R. Newman]

When I report spam, Spamcop tells me my average reporting time. For
years it stuck at 12 hours, so I assumed it wasn't calculating that. Now
it's gone up to 13 hours, so something must have happened.

How is the average time calculated, and does it take account of time
zones? I'm several hours ahead of the spamcop servers.
