Does the 90 minute clock ticks when game not in play?

In soccer, the 90-minute clock continues to run regardless of stoppages in play, such as injuries, substitutions, or other interruptions. However, the referee has the discretion to add stoppage time at the end of each half to account for these delays. This ensures that the total effective playing time is fairly represented. Thus, while the official match clock ticks on, the actual time for play is often extended.
