The Timer is a feature in Scratch that will record how much time, in seconds, have passed since the last time a project was opened or the timer was reset.

The timer is extremely accurate and the value itself is not affected by lag.[citation needed]

Related Blocks

The two blocks related to the timer.
The timer is associated with two blocks, both found in the Sensing category:

In Scratch 2.0, this block is also available:

  • When timer > (): This starts when timer value is greater than the input value.

How it works

The timer works in the following ways:

  • Continuously counts upwards by tenths of seconds
  • Cannot be paused or stopped (that would imply pausing or stopping the flow of time itself)
  • Shows seconds, not minutes or more — even when the current value is longer than sixty seconds
  • Resets only when a project is opened inside Scratch or by execution of the Reset Timer block
  • Continues even when its project stops running


when gf clicked
set [timer v] to [0]
    wait (0) secs
    change [timer v] by ((1) / (30))

This way is slightly less accurate than the timer, and can be affected by other scripts.[1]

Example Uses

The timer is commonly used in projects that require a clock of some sort, such as racing projects. Other uses include:
