UniKey Time provides real-time clock (RTC) features and this article will introduce how to integrate UniKey Time with your own projects by using the UniKey Enveloper Tool. Each UniKey Time has an embedded battery; providing the UniKey Time with a real-time clock. This means that clock inside of the UniKey is unique and independent from a computer’s system time. Protected software will expire on time, even if the user changes his computer's system time. Each UniKey Time has 16 Time Modules; each UniKey Time Module can be used to set an expiration date for protected software.

The UniKey Enveloper Tool is stored in UniKey_SDK\Utilities\Enveloper\UniKey Enveloper Utility

To protect software with the UniKey Enveloper is simple, and is described in the following procedure below.
