更改时间。时区,无需重新解析

I am dealing with time.Time objects that has been parsed with the wrong timezone. They internally have a UTC tz but the original data come from a legacy MySQL database that internally store datetimes with the timezone Europe/Paris.

I would like to change the internal timezone of the time without reparsing it. I have tried the time.In() function but it does not solve my use case because it return the same time for another timezone.

My ultimate solution would be to use https://golang.org/pkg/time/#ParseInLocation to recreate the date from the value of the original with the proper location. However if this could be avoided this would be better.

Any thoughts ?

Thanks.

    Can you just Add a fixed offest to them?

    t,_ := time.Parse(...)
    t = t.Add(-4 * time.Hour) // or whatever offset makes it work
    
    // t is now correct utc time
    // In should work less badly:
    localTime := t.In(myRealLocation)
