An apparatus is provided that includes a processor and a memory storing executable instructions that in response to execution by the processor cause the apparatus to at least perform a number of operations. The apparatus is caused to receive time information over a packet-switched computer network, with the time information including a current standard time, time-zone offset and timestamps that define a predetermined timeframe. The apparatus is caused to calculate a current local time from the current standard time and time-zone offset, and including an adjustment of the current local time in instances in which the timestamps indicate that the current standard time is within the predetermined timeframe. And the apparatus is caused to cause a clock to be set to the current local time.
