logmerge merges multiple log files into a single stream, preserving the total ordering of events across the multiple log files.
- Supports multiple timestamp formats
- Date and time with either fractional seconds or comma-separated milliseconds
- Integer or floating point time_t (base-1970)
- Can tag each merged line with an arbitrary text tag per source log
- Can color-code lines per log (using ANSI escape sequences)
- Assumes all timestamps are UTC. The currently-supported timestamp formats don't support a timezone tag.
- Timestamps are not reformatted. If merged logs use different timestamp formats, the merged log will expose that.
