In the early noughties I ended up being called in as a consultant to sort out a somewhat broken Novell eDirectory. Password changes working sporadically, details not propagating sometimes - you probably know this story.<p>I found a NTP stratum 1 source on site that someone had bought and forgotten about and the internet was available. DNS was also broken for IP and IPX/SPX was a bit special. I fixed up DNS and registered some host names and so on. I removed some odd routes in SPX and IP. I put all partitions on the three central office boxes and distributed the rest. I ran an awful lot of dsrepair and watched a lot of dstrace with various flags until the red turned to green. I'd get a partition into a decent state, then drop the replicas and rebuild them from the first one - all lots of fun.<p>Anyway, it was DNS and NTP (it always is). That isn't the real punchline ...<p>The company was called First Great Western (1)! I must stress this was not the time sources for their trains and operations equipment which was totally separate and properly managed by qualified professionals. Their general office IT needed a bit of a hand.<p>So I can lay claim to bringing time to GWR, if you squint hard enough! A few years later I did a similar job for ScotRail, when they too still had Novell office servers. I used FGW's servers as sources - it seemed appropriate 8)<p>(EDIT to add):<p>(1) <a href="https://en.wikipedia.org/wiki/Railway_time" rel="nofollow">https://en.wikipedia.org/wiki/Railway_time</a> - mentions GWR in line 1 and links to all the other related info.
