# How to figure out if a certain time has passed

so what i am trying to do is create a jail system similar to ridgeway or new haven county where when you get jailed, you have a timer. example:

i get booked for 10 minutes.
i leave for 5 minutes
and it says 5 minutes left

so, how would i do something similar to that or how would i figure out how much time has passed

When you get sent to jail, get the time using os.time. When I leave the game, use os.time again, and subtract the start time from it to get the amount of time you have been in jail.

You could use wait but generally it is unreliable.
Use tick time.
Here’s an article:

So, it would just be

``````--when jailing
plr.Data.JailStartTime = os.time()
plr.Data.JailTime= sentenceTime -->> 30

-- when joining
plr.Data.JailTimeLeft = os.time() - plr.Data.JailTime
``````
``````--when jailing
plr.Data.JailStartTime = os.time()
plr.Data.JailTime= sentenceTime -->> 30

-- when leaving
plr.Data.JailTimeLeft = os.time() - plr.Data.JailTime
-- upon joining, if there is time left, send them to jail and wait out the time``````

So, what will it be when 30 mins has passed? 0 or a negative?

Am I supposed to multiply sentence time by something? Because about 30 minutes have passed nd its still above 0

I think you should check if the specified time has passed like this:

``````local JailTime = 10 * 60

plr.Data.JailStartTime = os.time()
plr.Data.JailTime= sentenceTime -->> 30

plr.Data.JailTimeLeft = os.time() - plr.Data.JailTime
if plr.Data.JailTimeLeft >= JailTime then
print("Jail time is over")
else
print("Jail time is not over yet")
end
``````

Update, I figured it out. Thank you all for trying to help!
