When does the clock start ticking on a time-limited license?

This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP.

Timed licenses can be provided in two forms:

1. “Time-limited” licenses have a set duration that starts when the license is activated. This means that time-limited licenses can be held in inventory, knowing that they won’t run out before use. The duration is set in calendar days (strictly 24-hour blocks, so a 30-day license activated at 4pm expires at 4pm 30 days later).
   
   The expiry date and time can be predicted accurately if you know the duration and the time and date of each activation. See Can I be automatically informed when a license is activated?
   
   If a license allows multiple activations, the expiry date and time of each activation is set by the date and time of that activation, which means they are unlikely to be exactly the same.
   
   
2. “Expiry date” licenses have a specific expiry date that is set when the Product Key is created. (That is, they should not be held in inventory because their usable period is reduced, or they may even expire).

For demo licenses, you normally create time-limited licenses, using your specific OEM ID.

For evaluation licenses, you normally create expiry-date licenses, using OEM ID 0x0B (HMR) or 0x63 (HHR).
