I use ntp and this: https://www.npl.co.uk/msf-signal https://www.npl.co.uk/msf-signal I set my wrist watch manually. That's my time of first resort. It's slightly inaccurate but very, very reliable and handy (by definition!) I bought it about 15 years ago and its solar powered. Never failed yet. My phone keeps decent time but the battery needs charging - fails very infrequently but needs waking up. My laptop keeps a decent tick. It has a fairly decent local oscillator and ntp with several sources. Similar probs to phone and takes a while to boot. My three GPS synched ntp stratum 1 servers (RPis) that I keep in the office keep a very good tick. For my needs, consistency is more important than real accuracy but I do like to see sub millisecond accuracy available. It makes log analysis a lot easier.
