Internet time sync - NOT amateur radio

For 10m WSPR, I usually sync time using my atomic clock in the shack. For 8m FT8 and WSPR, I usually sync to internet time using the built-in sync with Windows 10. For some reason (too busy?) this sync was not happening earlier. I shall try again later. As far as I can tell my PC clock error is just a few seconds at most, so I hope this is OK for now.

Digital modes and time synchronisation

Many digital modes need the PC clock to be accurate. To this end, many use online time servers for this purpose. 

For some time now I have not bothered and use Windows 10 to do the syncing. To do this you have to make sure that Windows 10 can synchronise. Once a day seems to be adequate, although I have habit (probably not necessary) of doing a re-sync when I enter the shack.

If you have Windows 10, this may be all you need.

PC time syncing

Many digital modes like WSPR and FT8 depend on accurate timing.  

For the last few weeks I have just used Windows 10 to sync PC time.  As a matter of habit I do a re-sync perhaps once a day "just in case".  

Judging by results on FT8, I am perfectly sure this is fine. In the past I used special software for this. My advice is do not bother. 

Make sure your settings for time automatically sync. This is extremely easy.

Time sync

In the shack I have an Asus laptop that is several years old, so I would expect the battery to be losing capacity, In the past I used an online time server to sync to internet time when using WSJT-X. I have found this a waste of time. 

Every morning, I resync the PC clock using the facility in Windows 10. I find that this is perfectly fine. Occasionally, I resync the clock "just in case", but get the feeling this is overkill.

So, I do not think anything special is needed.
