TOTP now has a Time Machine

totp now has the --time, --forward, and --backward options that are used to manipulate the time for which the TOTP code is generated.

The --time option takes an RFC3339 formatted time string as its argument and uses it to generate the TOTP code. Note that the --forward and --backward options will modify this option value.

Examples with --time:

$ date '+%FT%T%:z'
2019-06-01T19:58:47-05:00
$ totp --time $(date '+%FT%T%:z') --secret seed
931665
$ totp --time 2019-06-01T20:00:00-05:00 --secret seed
526171

The --forward and --backward options move the current time forward and backward by their duration formatted arguments. See Go's time.ParseDuration() documentation for more details on this format.

Examples with --forward and --backward

$ totp --time 2019-06-01T20:00:00-05:00 --backward 3m --secret seed
222296
$ totp --time 2019-06-01T20:00:00-05:00 --forward 30s --secret seed
