Timestamp is not in order

[kaiduanx]

The issue is that the timestamp is not in the right order. The time stamp of the log at 59 line is older than the timestamp of the log at 64 line. I only commented out the runBenMark() function.

Hi kaiduanx,

I think the issue is related to #28 where log messages at the beginning of the file can sometimes have a negative nanosecond timestamp (notice the little dash character - after the decimal point). The timestamps are still in order; it's just that nanosecond count is printed out as a negative value. I suspect the fix may be just to add an if-condition in the decompressor to check for this case. However, I'm not able to reproduce the problem on my setup.

Could you send me your log file, so I can verify the fix?

Best Regards,
Stephen Yang
