I reinstalled Windows 10. Windows 10 has the correct time zone. However, Gmail is 2 hours ahead of me (+10 GMT), while I am in +8 GMT.
I checked this Q/A and found no current answers.
I see the wrong time on the right hand side of each email in my inbox. For instance, at 18:00 my time, if I see a new email, it will display 20:00.
Email I send has an email header:
Delivery-date: Mon, 16 May 2016 20:39:53 +1000.
Any current answers would be appreciated. Google doesn't really help much on this issue.
Update: I answered below that updating my Windows timezone resolve this issue, but in the time since, the original symptom has re-emerged, for an unknown reason. i.e Local Windows timezone is
+8GMT, Google Calendar timezone is
+8GMT, but gmail emails in my inbox at 13:00 (+8GMT) my time are displaying as 15:00 in gmail.
Update2: Windows time, although reset to
+8GMT, was still 2 hours behind, despite my PC connecting to the Internet for the correct time. Manually setting my time to the correct time resolve the Gmail issue.
