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.
