the server timezone may not match the local server time while comparing time.Please check the below code.

from datetime import timedelta

current_time = str(datetime.now() + timedelta(hours=5.5)) # '2022-05-13 13:37:45.063621'
current_time = current_time[11:16] # str 13:37
current_time = float(current_time.replace(":", ".")) # float 13.37
----------------------------
if current_time > your_float_field:# 8.25 > 8.0 # Checking the time with float field.

Hope it will be useful for you.
