Hi PineTreeWild,
It will take less than 10s to finish the sync with 1PPS in the begining.
The sync process is that:

  • CPU detects sync pulse and measures it’s period with sub-microsecond precision

  • If period is within 0.01% of target value for few consecutive periods signal considered to be valid and system will sync to it.
