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.
Currently, we do NOT provide the time calculation for adding time.
If you want to calculate the adding time, you can done by yourself.
For example, recording the timestamp for 45-mins end and then using the live timestamp to minus the 45-mins timestamp. Or any other ways can try.
Overtime only provides "status" and does NOT provide time calculation.
