    I use three tools. An inexpensive world band radio (tuned to one of the time 
    server frequencies) a stopwatch with multiple lap time capability and a 
    mini-cassette recorder. Just before a pass, start recording on the tape and 
    start the stopwatch running synched as best you can to a significant minute 
    (such as XX:00, or XX:10, etc.). Mention the start aloud, so that it 
    registers on the tape. Then click a lap time for each event you want to time, 
    announcing the clicks for the benefit of the recording. After the pass, you 
    can review the tape and jot down the timings and figure out which times 
    correspond to which events. The time server makes it easy, since each minute 
    is also announced on the radio.
