A.S. So first of all, my geographic location is Italy
I participate to a mailinglist where they told me that I have the wrong time, my bios is set to UTC (checked yesterday).
My boot code was tz=GMT+1 and my time was right but not for mailinglist
Now i use the example
in this page (tz=CET-1CEST,M3.5.0,M10.5.0/3) but my clock go foward by 3 hours respecto to italian exact time.
I understand little of time zones , what did I do wrong?
