Mitchell Janoff has been collecting and restoring master clocks, slave clocks, and precision frequency standards for the past ten years. His interests are primarily in time keeping and time distribution with a focus on clocks made by the Self Winding Clock Company of New York (SWCC). He has over twenty SWCC clocks, all of which receive hourly synchronization signals from a computer based "master clock" every hour on the hour. or more information on synchronizing self winding clock see the 1995 article from the NAWCC Bulletin "Self Winding Clock Synchronization". |
