No, this might help you to find the end of the grace period.
When you install a TS Licensing Server without activating it, or
activating it but without installing permanent licenses on it, the
LS issues temporary licenses to your clients. These temporary
licenses last for 90 days.
So assuming that you installed the TS Licensing Service at the same
time that you installed Terminal Services, you can check in the TS
Licensing Manager when the first temporary license was issued to
find the date when you installed TS and TS LS.

Here are the details:
