WWV is a long way from Australia and only available with good
A GPS receiver will give accurate seconds signals, even if there is
however it is not easy to identify which second. In the course of a
year it is quite

The GPS may drop out, so a disciplined oscillator is in order, but
how can you get

With a small 4 channel data logger I can then record a clock for a
year and its
relationship to UTC, temperature and barometric pressure. I would
a battery backup power supply for the TBolt.
