Fucking Time Propagation (lemm.ee)

Just bought the GWM 5610U-1C. It was a tough decision choosing between the DW5600 and this, ended up choosing this because the atomic time keeping is cool.

However, I'm a tad annoyed that the time doesn't perfectly match with time.gov and time.is since the atomic sync doesn't account for time propagation, so there's like a fraction of a second delay that's noticeable. Other than that, the watch is fantastic and has most features I would want. (I wish it had barometer and altimeter stuff, maybe even compass, and dive rated so I can press buttons underwater)

That would bother me too. But wouldn't they have to account for varying lag?

Yeah, that's what I'm asking here. Annoyed that this watch doesn't account for time propagation from the fort collins tower to here by transmitting back and forth to see the delay. But some @[email protected] above explained that I would need a huge antenna and a bunch of radio know how to set that up so it can go to fort collins. Which I can't believe I didn't even think of.
