The "Real-time data" interface has a "Kick-off timestamp" field. You can combine match status and formula to calculate match progress time

"Kick-off timestamp" will change in real time

When the "match status" is the first half, the returned "Kick-off timestamp" is the kick-off time of the first half.

When the "match status" is halftime, you can stop time calculation and directly display the halftime status.

When the "match status" is the second half, the returned "Kick-off timestamp" is the kick-off time of the second half.

How to calculate the time for overtime?

Overtime only provides "status" and does not provide time calculation.
