How it's used
Focuses specifically on the act of monitoring duration rather than just checking the current time. It is commonly used in competitive or task oriented contexts where precision matters. When someone asks you to perform this action, they are essentially asking you to act as a stopwatch.
Examples
The race has started, are you guys ready to record the time?

Common mistake
Do not confuse this with 睇時間, which simply means checking what time it is on a clock or watch. Using 計時 to mean checking the time is incorrect because it implies an active process of tracking a duration.
