Default Do you turn off "location access" in all the apps that don't need it?

Thanks Jeff.
What I love about *your* responses is that you *back up* what you say.

So, you can be *believed* because you have credibility.

I believe you when you say that the Android clock gets its time zone and
time from the carrier signal.

And, the fact you *tested* that (on WiFi) is great proof of that.
And, that GPS doesn't help the clock drift (I can't see how it would since
the admittedly extremely accurate atomic clock *in* the satellite isn't
sending *that* signal to the phone, is it?).

Bottom line is that if you want an accurate clock,
you need to leave cellular turned on.

That confirms what I had thought.
So, in effect, the clock (and all those other apps) don't *need* location

So why do they bother to force users (who don't know any better) to allow
location access when the clock (system) app is first installed by the

What *advantage* is it to the clock app, or to the system manufacturer (who
installed the clock app in the first place) to *require* location access?

Makes no sense to me.
Does it make sense to you?

What do they gain?
What can they do with it in a clock app?
