Custom format Date/Time field not working

[Guest]

Hi

I have a field in a table of type Date/Time. All I want is a value for year
in that field, so I have created a custom format of yyyy.

When I try inputting values in that field such as 1999, a dialog pops up
saying the value entered isn't valid for this field.

I also had an input mask of 9999;0; and at first I thought that this was the
reason that the problem was occuring, but after removing it, I am still
getting the error dialog.

It is quite annoying because I cannot see where I have gone wrong in the
table design.

If all you want to store in this field is the year, and not all the date,
then change the field type from Date/Time to number, there is no need for the
date time type.
That way you wont get an error while storing the year only.

The reason for that error is that 1999 is not a valid date.
A valid date consists of a Month, Day, and Year.

If all you want is the year, change the field datatype to Text or
Number. If you do have a valid date and want to display just the year,
then set the Format property of the field to
yyyy.
