Well how do you think TOTP works?

TOTP works by having huge margins of errors (minutes worth). The original post is suggesting using time of day as seed.

The point was you could do similarly here. Just have a margin of like 30 seconds (or whatever). I never said you have to do this to nanosecond precision.
