If the wave is getting bigger, it causes the time to grow a little bit. If the wave is trying to contract, it reduces it a little bit. So, you can see this oscillation in time on the clock.
I'll just tell you the way it is. You ask me what time it is and I'm gonna tell you how to build a clock.
You can have your own watch and always doubt it. If I had a watch I'd probably always be doubting it or the batteries would be dying. I just know that people always have trouble with their watches, and that's why I like public clocks.
Digital is a disaster. No digital radio has the correct time and they don't even agree with each other.

They're pretty accurate, the clocks in mobile phones.
I got players with bad watches - they can't tell midnight from noon.
Ah! the clock is always slow; it is later than you think.
One [method] is by a Watch to keep time exactly. But, by reason of the motion of the Ship, the Variation of Heat and Cold, Wet and Dry, and the Difference of Gravity in different Latitudes, such a watch hath not yet been made.
You can never know how your clock runs. But it does run - and always faster than you think.
