Okay. NTP can do that easily, if you run nothing else on them. > It is not so important how well these match to GMT, ... ...to you.

I regret to inform you that NTP was engineered to work for other people, too. Feel free to commission your own product or to hack the - freely available - source to NTP. That does not mean that configurations don't exist that would suit you better than what you have now. Perhaps a PPS source distributed to all your nodes? That should get them in very tight synchronisation. If you want them synchronised the soonest after you come in in the morning, I would recommend not turning them off overnight. Not just to be lazy, although it is also the simplest solution, but mostly because it minimises frequency changes all around. The less the server's frequency excursions, the easier for the clients to follow them. The less their own excursions, likewise.
