Date set information for custom field

Question

We are trying to figure out a way to know/get the date a custom field gets set for reporting purposes.  For example, we have a Yes/No select list field that gets set after an issue gets created.  Is there any way to get the date this was set internally?  If not, can we get the information we are looking for a different way?  Our only other way around this is to change the field to a date field and have the user enter in the date they set the field but we don't like this option.

I believe you can do it by adding one more "Date" custom field to the same screen where you have "Yes/No" and injecting JavaScript that will populate the date field when a "Yes/No" is changed.

I think you have two possibilities:

When you create an issue (status Open) you could add a transition from Open to Open. In this transition you use a screen with this select list (remove it from edit screen) . Now you can set a custom date (time) field and populate it with the current date (time) in the postfunction of that transition.

The other is to use a scripted field (script runner) similar to this example:

Since I'm not an scripting expert, I can't give you the correct script, but maybe others can help.

Changed operator can only be used with Assignee, Status, Resolution,Reporter, FixVersion and Priority but not with custom fields (at least at the moment).
