Hi everyone I would like to know how can we calculate time duration between two times my aim is to find time difference and see if its greater then the user would get a message saying YOU ARE LATE BY __ HOURS __ MINUTES . I wasnt able to find any api but I tried a workaround which just subtracted The time set by me and the current if its less than 1 report 1 hour late else report you are on time However this was working fine until let’s say my time to calculate from is 9:30 so if the current time is 10:00 it should return 1 hour but it’s saying 1 hour late so can anyone show me how to calculate time difference these are my blocks.

What is the source of the two times you want to check? Are the times being selected, or typed in or determined by the device’s clock?

Currently the time with which I want to check if he is late is is just in the blocks I.e 9:30 am and the other comparison time is the user’s current time. To simplify it is a attendance system which checks that if the user is late than the reaching time which is 9:30am warn him with a alert block saying if he is late by ___ hours __ minutes
It is hard to understand what you are saying it is sounding too confusing, Can you please present your problem in a more clear way.
To simplify my statement I need to calculate duration between two given times one of which is the system current time
Hi there,
You can view a project here that will calculate the difference between a given start time and the current time.
This project calculates the total minutes between the current time and the given start time.
This is done by calculating (difference in hours * 60) + (difference in minutes)
(Eg. if the event starts at 10.30 and it is currently 9.45, the total minutes = (1 * 60) + (-15) = 45)
If this is total number of minutes is 0, it says that the event is starting right now.
If this is greater than 0, it says that the event starts in X hours and Y minutes.
If it is less than 0, it says that you are late! The event started X hours and Y minutes ago.
(X = total minutes divided by 60, Y = remainder of total minutes divided by 60).

I simply use a Google sheet having 3 columns
start time
end time
result (sheet calculation of end time - start time)
In my code, I update start time and end time and read result. It always works and the code becomes simple.
Thanks @muneer for another solution, It’s a good idea but I want this to be an offline feature
