I'm trying to do something which should be simple: Cause the current date to be printed in the header. Under File>Print Settings>Headers and Footers there is a nice form, and to the right an arrow that opens selections, just to make it easy. For example, selecting "File Name" inserts an object that looks like <<FileName>> which works. Same for <<PageNumber>>.
When I select Date I get:
FrontEnd`CurrentValue[FrontEnd`$FrontEnd, {PrivateFrontEndOptions,
"DialogSettings", "HeadersFooters", "DateFormat"}]
which shows up just like that in the Header. Useless.
I did once do that and get <<Date>> which did put the date in the header, but I've never had it do that again.
This should be completely easy -- any suggestions?
