This tool can be used to convert timestamps in a log to any desired timezone while tailing logs. Eg. In case your logs are in UTC and you want to view it in a different timezone say. Asia/Kolkata (IST), pipe the logs through tztail
.
## Example usage
$ cat somelog # A log in UTC
2018-11-03 19:47:20.279044 I mvcc: finished scheduled compaction at 104794 (took 748.443µs)
2018-11-03 19:52:20.282913 I mvcc: store.index: compact 105127
$ cat somelog | tztail --timezone Asia/Kolkata # Timestamps converted to IST
2018-11-04 01:17:20.279044 I mvcc: finished scheduled compaction at 104794 (took 748.443µs)
2018-11-04 01:22:20.282913 I mvcc: store.index: compact 105127
It allows to specify a custom format as well.
## Example usage
$ cat somelog # A log in non-standard format
2018-11-03 20:07:20 mvcc: store.index: compact 106120
2018-11-03 20:07:20 mvcc: finished scheduled compaction at 106120 (took 933.25µs)
$ cat somelog | tztail -t Asia/Kolkata --format "%Y-%m-%d %H:%M:%S"
2018-11-04 01:37:20 mvcc: store.index: compact 106120
2018-11-04 01:37:20 mvcc: finished scheduled compaction at 106120 (took 933.25µs)
