My go version is 1.11.

When I set time.Location, then …

==================

The feature of golang is goroutine, and it is a normal situation that get time in different goroutine.
But only can set time.Location in one goroutine. So the Data Race is inevitable.

And there is the replay from agnivade
“It is not a bug. Please synchronize access to time.Location using synchronization primitives in the sync and sync/atomic packages.”

But there are lots of place that time.Location used by time package of golang. For example: time.Now(), time.locabs()
I can’t change them.

So, What should I do ? Please help me.
