I recently purchased a Feitien C200 and it appears to be 93 seconds slow (I'm using pool.ntp.org). If I run the command "oathtool --totp --time-step-size=60 --start-time='1970-01-01 00:01:33 UTC' <SEED>", I get a correct match. My question is how to define this in the users.oath file? Searching through the archives, I see there was a proposal to add "TOTP/S60-93" to the start of a config line, bit don't see support for this in the source.
