Strange gc log output

I was wondering if anyone might know the cause of the following behaviors
illustrated by the log excerpt below:
1)  Huge jump in the timestamp printed to the GC log (150 days in this
example .. though the process was started last night).
2)  All of the GC timings are reported to be 0.0000000 seconds.

I'm running the 64-bit JVM - version 1.6 update 7 on x86 Solaris.

I tried to attach a zipped copy of the full gc log, but it exceeded the 100K
limit.

Any help would be appreciated.
