Not usually unless the sun comes out for short periods of time so you can see what time it is.
Because it is a electronic device!

Yes and you can use about anything as a sun dial as long as it is stationary. Mark the ground from day to day to mark each day, and of course it would not be effective on cloudy days.
grey day
1. Can only tell the time, not the date. 2.Obviously needs sun, not clearly viewable on a cloudy/dark day. 3. Needs to be in a certain position in order to be accurate.
The good is that you don't have to put batteries in it or use electricity. The bad is if it is cloudy.
A sundial is a round dial with a pointer for the sun. When placed correctly it will read the time of day.

A sundial uses light to measure time. Of course, it doesn't work well in the evening and on cloudy days.

He used a portable sundial.
The sundial itself doesn't really change day to day, or even year to year. They are generally fixed to the Earth and are not, in general, portable. The shadow cast by the "gnomon" (the pointer of the sundial) does move moment by moment throughout the day, and slightly from day to day.
The sun dial was used for telling time. The sundial would cast a shadow so people know what time of day it was by where the shadow fell.
a simile for a cloudy winter day
Clear, party cloudy, partly sunny, broken clouds, and overcast.
