feat: add support to unix timestamp

[RodrigoDornelles]

It is interesting to support the Posix standard as one of the formats compatible with the parser.

Hello. Sorry for my slow reply and thank you for your suggestion.

Could you clarify what Posix standard/pattern/format you mean? (link?)
Or you are suggesting we should recognize 10digits numbers in the possible range (e.g. 1717236990) as a timestamp?

If it's the latter, I'm not sure if we should include it in the default setting.

That would be it, you wouldn't need a decorator around the function, maybe it supports unix:1111111111, it's not human readable which is what the lib proposes, but it ends up being useful anyway.
