That is because A1 probably starts at less than 5 hours, and Excel doesn't
like negative time.

What would you like to happen if A1 is less than 5am to start with?

I tried the first example you gave =A1-TIME(5,0,0) - however my result
is
########## that no matter how wide I make the column it keeps doing that.
I
got the same result with your second suggestion. Do I need to select a
different time format?

One way:

=A1-TIME(5,0,0)

Alternatively, since times in XL are stored as fractional days, you
could use

=A1 - 5/24

which is just a bit more efficient than using the TIME() function.
