Improving the accuracy at the communication time filled in on my log book
| It was a very difficult
thing to maintain accurate time. Recently, it is able to correct an internal time of my personal computer by obtaining accurate time information by using Internet. However, it is very annoyed to turn on the personal computer every time, to confirm accurate time, and to describe time to log book. The electromagnetic wave clock is used as a method of solving the above-mentioned inconvenient. The photograph is a clock which receives Japanese standard time by the electromagnetic wave and proofreads at time. |

| Recently,
it is able to buy this radio controlled clock with $20 or
less. Japanese standard time is transmitted from Mt.Ootakado in Fukushima Pref. in Japan by using the long wave as 40KHz. This standard wave transmitting station has been operated by Communications Research Laboratory since June 10, 1999. |
