Original GitHub issue: https://github.com/asciinema/asciinema/issues/252

When I did some post-editing of an ASCIInema v2 cast I'm currently experimenting with, it occurred to me that it would be very useful if I could use the (currently still imaginary) command line parameter
--offset <time> or
--offset <line>.

Such a feature could be useful even beyond the mere editing of an asciicast file: you could directly point someone to a particularly interesting point in a replay, or even create a HTML link scheme for starting the re-play of an uploaded file on asciinema.org from that point.

There's already ?t=123 parameter supported on the site to start playback from given second (see "Customizing the playback section" in sharing doc).

For the in-terminal playback, we already have #201 opened for that, and there's old PR #180 which needs some work.
