All they want is that the clock face on their smartwatch/clock on their smartphone/clock in the bar at the top or bottom of their screen display the correct current date and time, that their file manager report the correct creation/modification date and time for files, etc..
Not always!
For example, we make an embedded IoT product that allows up to six date/time displays to be shown simultaneously, each configurable to use a different time zone. In that particular use case, the 'determine my time zone automatically' method is not only irrelevant, but can be positively harmful.
There's a company that makes a handheld device that
1) uses the "determine my time zone automatically" method
It depends on what is used to determine the time zone automatically, a geolocation which can be ambiguous if you are close to some border, or e.g. the telecommunication network used by your handheld. Even the latter can be wrong. For example, I've visited the Canary Islands located in the Atlantic, in zone UTC+0, but these islands belong to Spain which is located in the zone UTC+1, so my handheld selected UTC+1 automatically, and I had to correct it manually to UTC+0 to have the real local time.
