There were "Standard Clocks" wired into the Western Union, or some sort of telegraph system, and ever hour on the hour the "Standard Clocks" were all zeroed in, including the second hand, to that exact hour. I remember seeing many such pendulum clocks with the electric zeroing in "fingers", that maintained total accuracy every hour. Thus, there have been many photos of Engineers and Conductors comparing their pocket watches with the Standard Clock in the crew office.
Here is one of the station clocks that would have it's time adjusted by the master clock. Every hour the clock would self wind itself via the battery.
