Answer 1

For full explanation see Dealing with Multiple Time Zones in SharePoint 2010

var user = SPContext.Current.Web.CurrentUser;
// Always perform a Null-Check on SPUser.RegionalSettings
if (user.RegionalSettings != null)
{
    return user.RegionalSettings.TimeZone.UTCToLocalTime(listDateUtc);
}
else
{
    // User didn't set a time zone, so use the one from the Web
    return SPContext.Current.Web.RegionalSettings.TimeZone.UTCToLocalTime(listDateUtc);
}
