Abstract
A technique involves the use of an electronic device having a real-time clock (RTC) circuit. In particular, the technique involves obtaining an RTC value from the RTC circuit. The RTC value is based on a previous time value and being arranged to represent current time. The technique further involves generating an adjustment factor arranged to adjust for imperfection in an oscillator of the RTC circuit, and providing a new time value based on the RTC value and the adjustment factor. The new time value represents current time at least as accurately as the RTC value.
