My MacBook air clock loses time

If the date or time is wrong on your Mac - Apple Support

• Confirm "Set date and time automatically" is selected.
• Confirm you are not using a VPN, any non-Apple "firewalls", "anti-virus" junk or anything else capable of blocking or interfering with your Mac's ability to communicate.

Were any of the ideas - to check and change settings ~ in the linked support article - helpful?

Those are usual suspects; then maybe try one or another system reset, to troubleshoot Mac.

Or this ~ to help troubleshoot; can take up to 20 minutes to check the macOS, in Safe mode:

SMC, may help.

Or perhaps try NVRAM/PRAM reset?

To verify an act of Setting the Time, is only first item among several should one be

interested in Troubleshooting the Device. ~ Could be a power reset or logical reset

may help. Even half-hour 'Safe mode' systems check on startup, may work by itself.

Those were a few items that I'd check and use as tests, to attempt a DIY reset.

Or you could try and contact Apple service, to see what suggestions they offer.

All together, the matter is really up to you; to try these items and see if any help.

As for me, I'm inconsequential. And I'm at home, not representative of Apple; &

certainly not compensated. ~ You may Contact Apple to see what they suggest.
