San Diego, Computer Center Lines: 21 someone just told me that heathkit is making a device that listens on the various frequencies that have the time transmitted on them. i don't know what frequencies these are. if you have a radio with some shortwave bands you may have come across one; you hear a sort of blipping tone and then every so often (once a second i think) you hear a man's voice give the time. it is given in what used to be called greenwich mean time (now its called universal something or other). the time reference they are using is an atomic clock. these broadcasts are by the national bureau of standards. anyhow, back to this heathkit device; it has an rs232 connection on it. it is designed to be hooked up to a computer. i guess one of these frequencies has the time transmitted in a way that can be decoded by a computer? i guess you can have your computer ask it every so often what time it is, or maybe the heathkit box spits out the time on the rs232 connection every so often. i have no idea about the format of the data into or out of of the rs232 connector. so, what i was thinking is that if you get a time server going you might want to get one of these gizmos.
