How can I get a more precise time?

How can I use hl to get the timestamp after milliseconds?

Run hl --help and find

  -t, --time-format <FORMAT>  Time format, see https://man7.org/linux/man-pages/man1/date.1.html [env: HL_TIME_FORMAT=] [default: "%b %d %T.%3N"]

So, you can either

• Pass a command-line option, i.e. -t "%Y-%m-%d %T.%9N" to show date and time with nanosecond precision
• Configure an environment variable with the same value
• Or configure it in the configuration file

The complete guide for the format string syntax can be found here.
