Small temp and small time

We know a fellow who is about our age and suffers from dementia.  She was supposed to take him to a physician today for a check-up but we worried that the roads might be too dangerously slippery with ice. Later, she called and said the roads were not bad at all.  Some of our weather apps said the outside temperature was 32 degrees but some said it was a little warmer, maybe enough to not freeze.

I have four different weather apps on my iPad and they rarely agree totally.  Besides, we are often said to live in Stevens Point but that can point to a rather large area.  There are occasions where one app or another says it is raining or snowing when outside of our house there is no trace of either.  We are used to clocks, weather reports and sometimes computers or house phones not agreeing with each other.

The same sort of disagreement happens with time readings.  My watch, my computer, my tablets, various clocks around the house can disagree as to what the exact time is.  I used the labels "small temp" and "small time" for times when I am interested in the exact time or temperature but I have learned that idea is somewhat mythical.
