Pairing historic time with current time

[retrac]

I am trying to make this formula work:

=IF(AND($A$1<=0.451388888888889,$A$1>=0.397916666666667),1,2)

$A$1 is the current time. The formula =now() . It is 1/25/2018 20:03 a the time of this post.
0.451388888888889 is one time. It is 1/0/00 10:50
0.397916666666667 is the other time. It is 1/0/00 9:33

Since the dates of the current time and the historic times do not match, the formula does not work properly. I am fine using dates, but do not need to. I really just need the times to align with the current time, so the formula will work.

I am open to changing the decimal times to something else, or arranging a new formula. Thank you.

 

[sheetspread]

=MOD(NOW(),1)

gives you just the time

so does

=NOW()-TODAY()

 

[retrac]

=MOD(NOW(),1)

gives you just the time

so does

=NOW()-TODAY()

Thank you! That is what I was looking for to align them. It works now.
