My analogue pips come before my digital pips, so my watch would be slow, not fast, if I was unwise enough to set it by the digital signal.

Digital is famous for "latentcy".

HD channels are delayed  from standard cable of the same channel here where I live.

This time site would encounter the time delay of the web, but it says it's within .2 seconds, so maybe it measures the delay before sending you the time, and corrects for it.

You can change the time zone.

This is the official time:

So, Your radio controlled "watch"  is not set to something,

it is the time by law for the UK.

There is a "digital" delay compared to "analog" received RF signal even if they are sent at the same time. This is because your digital receiver "buffers" (stores) an image of the received signal so that it can check for errors and build up a correct image using information distributed (timewise) in the received signal. The digital signal contains more information than the minimum amount  required exactly for this purpose.

This would not apply to a receiver that uses a dedicated time frequency (such as a simple self correcting watch which uses error detection but not error correction, maybe  more sophisticated watches/clocks will correct errors but it also allows for the delay in correction calculations) The simple watch will ignore an erroneous signal and wait for the next correct signal)

Good GPSs will even allow for the transmission time difference due to the distance from the satellite that it is referencing from. Some will average the reference from multiple satellites.

There are two main causes for the difference in timing between analogue and digital radio and TV signals.

The main cause, which is true of all digital transmissions, is that digital signals are all encoded in some way, so the transmitter has to encode the signal for broadcast and the receiver has to decode the received signal before playing it to you.

You can actually see this effect in action if you have an analogue radio, a cheap DAB radio and a more expensive DAB radio all tuned to the same station.

The analogue radio will play the signal first, then the more expensive DAB set, then the cheaper DAB set. The difference in DAB sets is due to better sets having faster processors that decode the signal faster.

The second only applies if you are getting the digital signal from a satellite, in that case the difference is caused by the longer path of the signal travelling up to a satellite in geo-stationary orbit then back to Earth. This is the cause of the 'satellite lag' you sometimes see in live news broadcasts where the two locations are linked via satellite feeds.
