    To time observations, I have used an electronic stopwatch with 10
    memories. It can be started at a known time using a separate clock or a
    radio time tick. Pressing the "split" button stores the elapsed time at
    that instant into a memory. This minimizes the workload during the
    observing run.
    
    The stopwatch also indicates time of day with excellent precision. Its
    monthly rate (that's how often I check it) is predictable within 3/4 of
    a second. Unfortunately, it's not possible use that part of the watch to
    "hack" the stopwatch function! When you select stopwatch mode, the time
    of day is no longer visible.
