I'll add this timestamp to the set of defaults for the final v0.10.0 version later today.

The documentation for the format files is here:

https://docs.lnav.org/en/latest/formats.html

The "timestamp-format" property in the format definition is an array of the formats to be tried beyond the builtin set.

Here are some example formats written by a user:

I think some of them define their own timestamp format.
