In one of our projects we needed to show the Modified date and time value in publishing page.
Not a big deal you would think. The only issue we had when using a FieldValue control is that the time that would be displayed was 1 or 2 hours later than the actual value.
After I changed this to a DateTimeField the difference was gone.
The only thing you need to add is a ControlMode=”Display” attribute to prevent editors from setting their own value in edit mode.
The difference is in the way the value is rendered. The FieldValue control does a ToString() and HtmlEncode on the value. The DateTimeField actually converts the value to local time by using the TimeZone class.
It’s all in the details!
