normtime

Normalize timestamps in log files to make them easier to diff.

Requirements

Linux

coreutils package for date
gawk package for awk

Mac OS X

Install Homebrew or your favored package manager.
brew install coreutils in order to get gdate.

Usage

Step 1: Grab the first timestamp in your log

head -n 5 my-logfile.log

[2019-10-09 15:34:02.471] manager.c: HTTP Manager logged on from 192.168.1.3
[2019-10-09 23:42:02.477] features.c: Setting call duration limit to 28800.000 seconds.
[2019-10-09 23:42:02.478] app_dial.c: Called SIP/192.168.1.2/13124450947
[2019-10-09 23:42:04.174] res_rtp_asterisk.c: 0x7fd1ac0091e0 -- Strict RTP learning complete
[2019-10-09 23:42:13.204] dial.c: Local/15555555555@context-00000001;1 answered

Step 2: Convert the first timestamp in your log to a unix epoch timestamp

Note: On Mac OS X, use gdate instead of date.

date -u -d '2019-10-09 15:34:02.471' +%s

1570635242

Step 3: Normalize!

./bin/normtime.sh my-logfile.log 1570635242 | head -n 5

[1970-01-01 00:00:00.471] manager.c: HTTP Manager logged on from 192.168.1.3
[1970-01-01 08:08:00.477] features.c: Setting call duration limit to 28800.000 seconds.
[1970-01-01 08:08:00.478] app_dial.c: Called SIP/192.168.1.2/13124450947
[1970-01-01 08:08:02.174] res_rtp_asterisk.c: 0x7fd1ac0091e0 -- Strict RTP learning complete
[1970-01-01 08:08:11.204] dial.c: Local/15555555555@context-00000001;1 answered
