Brooke, I find that the most annoying thing in the world* is a clock that requires you to cycle through 59 of the wrong minutes to get to the minute you want. So I designed my clocks to use one digit at a time setting on the minutes and seconds, but to cycle through all 12 hours in one go. For 24 hour mode, you might like having one digit set at a timem. Ideally, you'd set the timezone and let GPS set the clock via NMEA strings. Timezone can be difficult to calculate given the lat/long info - having the user set it as a number of hourse like -7 or +6 relative to The Center Of The Known Universe (Greenwich) is easier. Since DST is also quite difficult to calculate, many in the world of exotic electronic clock makers just provide a DST on/off flag for you to set manually twice a year. I don't have DST here in Arizona, so I don't think about it much. * Recently I encountered a clock that was even more annoying. It was a Seventies digital clock of the mechanical wheel type on an electric cooking range. The timesetting knob was key-shaped so you could only turn it a half-turn at a time, which incremented the clock by all of three minutes. Think how many turns it took to move it 6 hours! -- --David Forbes, Tucson, AZ http://www.cathodecorner.com/ _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
