Since time is expressed in mathematical equations, wouldn't that suggest it is real?...
No. The parameter, "t" can be eliminated from ALL equations as it is not a real observable. ONLY changes are observable.
I have made several posts explaining how time can be eliminated from ALL equations describing the world. Quickly, again:
Q1 is F(t) = expression A with several variables
Q2 is F(t) = expression B with several variables
Solve Q1 & Q2 for t and get
Q3 which is: t = an expression using the several variables of Q1
Q4which is: t = an expression using the several variables of Q2
Now as t = t we have:
Q5, which is: an expression using the several variables of Q1 = an expression using the several variables of Q2
In Q5 the parameter "t" does not appear; but we have how one real observable changes with a different real, observable variable's changes.
For example we might have the height of burning candle expressed in terms of the angular position of the moon on some specific night seen from a specified location. I. e. a direct relationship between two observables.
F(t) is more convenient, but leaves vague, what the t variable is; as it is a non-observable. Swings of a pendulum? Position of hands on my Timex watch, etc.
SUMMARY: Time is not an observable - only changes are observables. Changing observable A can always be related directly to changing observable B. Time is not essential in equations, only convenient, but a little vague, what its value is.
