Replace rdate by ntpdate in Raspberry Pi build
The Raspberry Pi does not have a persistent clock and needs to acquire the time from the net or manually at every boot. It includes rdate which is supposed to do that. I find that rdate, at least when run from a location in the UK, returns a connection refused message and the clock is started from the beginning of the Unix epoch. It looks as if it's getting an address from the pool which no longer responds to this protocol. My work-around is to replace it with ntpdate. I suggest this replacement is made part of future builds.
