Now
returns epoch, relative to UTC. "Await time" defaults to your local
time zone. If they differ, Now may not reflect the time you expected..
Try to set UTC as "Await time" time zone.
Also,
Now doesn't represent seconds since midnight, as expected by Await time.
In order to convert the number of seconds, as delivered by Now to
seconds since midnight (UTC), take modulo number_of_seconds_per_day,
that is, Now % 86400.
A third, but probably
unneeded measure, would be to strip the decimal part from Now, as I'm
not sure that "Await time" behaves nicely with reals. So instead of
"Now", you may want to use floor (Now % 86400) - and don't forget
about the UTC setting in "Await time".
