Automatically setting a clock of a network-connected apparatus

An apparatus comprising:

• a real-time clock (RTC);
• and
• a processor and a memory storing executable instructions that in response to execution by the processor cause the apparatus to at least:
• receive time information over a packet-switched computer network, the time information including a current standard time, time-zone offset and timestamps that define a predetermined timeframe;
• set the RTC to the current standard time, the RTC configured to keep the current standard time;
• 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
• automatically set a clock to the current local time,
• wherein the apparatus caused to calculate the current local time includes the apparatus caused to periodically check the timestamps and the current standard time kept by the RTC, and identify the instance in which the timestamps indicate that the current standard time is within the predetermined timeframe.
