As this biannual change always causes concern amongst our customers* we are posting it here.
This weekend marks the end of Daylight Savings time in the United States. If your local computer is set for daylight savings mode* this will happen automatically. vBulletin will see this as well and automatically adjust your time. The timezone information (GMT-X) will also change* this is normal. If the time is correct on your site there is nothing to worry about.
In the United States* the change will occur at 2:00 a.m. (local time) November 1st.
