"Once you start the app, there is a bit of a delay as it acquires signals from multiple GPS satellites and then it gives you the time. It requires no Internet connection to work."
How much delay? For normal use on land, there shouldn't be much at all ...unless you're indoors or otherwise have poor GPS signal reception. Of course, my "GPS Anti Spoof" app does the same thing as part of its normal operations.
