The more important time is the time it took on the server to process the
request, so the system time. The user time can vary, due to many conditions
such as their internet connection (56k vs. Cable), their location (you're in
USA, they're in China or something), and so on.

I would be more worried about the system time, for the user time is often on
their end.
