As I understand it, time-machine is basically a wrapper around "guix
pull" and the command you want to execute ... so you could use:

  guix pull --profile=path/to/a/profile --commit=...

And then call the guix from that profile:

  path/to/a/profile/bin/guix shell --container --mainifest=...


Maybe there is some more elegant way, but that should work...
