This is a soon to be released feature in uftrace, allows correlation with lttng kernel traces.

This fixes all traces being from boot time and helps with correlation.

Code looks good. Just some formatting issues. I'm not able to test it though.

I didn't read the code carefully but please make sure to handle backward compatibiliy since the previous uftrace data doesn't have utc_offset field in its info.

Incubator build is still broken. It needs the PR #28 to be merged first and then a rebase.

I should have replied earlier.

It assumes UTC Offset is 0. If there is a field named UTC Offset and it is NOT "0" it tries to parse the number. If it succeeds in parsing, it assigns the offset to the non-zero value.
