There has to be a name for this. Anyone?
Suppose I am timing an event like a Sun sight using a digital time display that shows seconds, but no fractions of a second. The time in the display really ought to be set half of one second ahead of the actual time. That way when I look at the device, it will display, e.g. 12:04:30 for times with the seconds of true time (UT of whatever) ranging from 29.5 to 30.5. The displayed time rounds to the nearest second. I think in practice it has been standard to display tenths when we're really worried about marking the time accurately to the nearest second. But what should the practice be if tenths aren't available??
