It is when doing any kind of tag search.  So org-agenda, mostly.

I'm not surprised you cannot reproduce it because it is dependent on
your local timezone.

Ah, perhaps I should make the issue clearer.

When I run this at 2017-11-01 20:55:30

(org-2ft "<now>")
1509594900.0

(org-2ft "<2017-11-01 20:55:30>")
1509569700.0

Therefore when org.el does a tag search for SCHEDULED="<now>", it will
not match <2017-11-01 20:55:30>, assuming that I have frozen my system
clock to that time.

Again, this is dependent on your local time zone.  Try setting your
time zone to America/Los_Angeles.

1. emacs -Q
2. Assume it is 2017-10-10 12:00:00 local time
3. Create an agenda file

* TODO thing
SCHEDULED:<2017-10-10 13:00:00>

4. M-x org-agenda RET m SCHEDULED>"<now>"

Expected:

thing shows up

Actual:

thing does not show up
