Human Time

Status: stable

Features:

Parses durations in free form like 15days 2min 2s
Formats durations in similar form 2years 2min 12us
Parses and formats timestamp in rfc3339 format: 2018-01-01T12:53:00Z
Parses timestamps in a weaker format: 2018-01-01 12:53:00

Timestamp parsing/formatting is super-fast because format is basically fixed.

Here are some micro-benchmarks:
