I would guess so.

you need its value to increment every act step.
referring to the frames field.

do i just place frames+=1 in the act() method?

That will get the frames field to increment upward. After which, you need to call the updateTimeDisplay method when needed:
?
1
if (frames%55 == 0) updateTimeDisplay();
Both can be done in one line of code using the following:
?
1
if ((++frames)%55 == 0) updateTimeDisplay();

so i just have to use

if ((++frames)%55 == 0) updateTimeDisplay();
in the act() method instead of using

1
2
frames+=1
updateTimeDisplay();
To clarify, this code:
?
1
if ((++frames)%55 == 0) updateTimeDisplay();
checks if frames is = 0 and if it is, it will call the updateTimeDisplay method which will show the time ever since the game started, is this logic correct?

Almost, you missed on a couple things. You left out that it increments the value of frames first and the check is not if frames = 0. The check is if frames (mod 55) = 0 (if the remainder after dividing frames by 55 is 0).

so once the frames reaches 55, it would stop calling the updateTimeDisplay method since the value of frames is !=0 after being divided by 55?

That is not what it suggests.

When the remainder is zero, frames is divisible by 55. That is when the timer display needs updating -- at the end of every "second".

i'm trying to do a timer than counts down but i'm having difficulties getting it done too... it seems to be stuck at "00mins 00 secs" when its supposed to start out at "3-7mins 00secs" and count down to "00mins 00secs" and start again at "3-7mins 00secs" again This is my current code:

 //to be implemented  
}
Do take note that i have created an actor that have this code inside too:
?
1

import greenfoot.*;
 
public class Cooldown extends greenfoot.Actor {}
I have a feeling that its probably this part thats wrong:

if (Cframes <= 0)
{
    Cframes += (3+Greenfoot.getRandomNumber(5)); //chooses a cooldown time between 3-7 minutes randomly    
    Minigame();
}
if ((((--Cframes)%55)/60) == 0) Cooldown();

You do not need a CoolDown class; and you do not need a TimeDisplay class. You only need the one SimpleActor class. Your CoolDown method should be an updateCoolDownDisplay method. Line 9 should be:
?
1
private int Cframes; = (3+Greenfoot.getRandomNumber(4))*55;
and line 47 should be:
?
1
if (Cframes == 0)
and line 52 should be be before that line and look like this:
?
1
if ((--Cframes)%55 == 0) updateCoolDownDisplay();
In fact, you should probably move the first if inside the second one.

so i should delete the Cooldown and TimeDisplay class and implement only one SimpleActor class then Line 6 & 5 would be changed to:
?
1
2
private Actor TimeDisplay = new SimpleActor();
private Actor Cooldown = new SimpleActor();
and for my act(), it should be:

    {
        Cframes += (3+Greenfoot.getRandomNumber(5)); //chooses a cooldown time between 3-7 minutes randomly

    }
}
along with my Cframes changed to
?

private int Cframes; = (3+Greenfoot.getRandomNumber(4))*55;
