The time scale and date display is derived from the file header, where the start time in seconds from Midnight Jan 01, 1970 GMT is stored. It is only as accurate as the PC system clock was at the time the recording was initiated. In order that a 24 display always be available, the first line of the plot is the hour at which recording was initiated, not 00:00 GMT as seen in the LDEO plots. Elapsed time is only as accurate as the crystal on the Dataq A/D board. Our experience with several of the DI-194 and DI-154 devices is that the sample rate is about 300 parts per million fast on all of them, so that about 1.0 seconds per hour is gained. This error can be negated by modifying the header element that stores the sample period to make it shorter by 300 parts per million. If the PC system clock was in error, it can also be corrected by changing the time information in the header. 0000347210 00000 n It's not long before the new dancer is feeling like an old pro!

We use a slightly modified WWVB-controlled wall clock (Atomix brand supplied by Chaney Instrument Company) to generate accurate one-minute marks on our recordings. We have attached a small aluminum foil reflector to the second hand. An external LED source and phototransister assembly is used to detect passage of the second hand past the even minute time. The HeliPlot detailed waveform display shows the marks as vertical blue lines. Most of the time, the wall clock is very accurate. At certain times of the day, it goes through an alignment routine with the WWVB signal.
