Hello,

I'm trying to change the color of the authors column for books added today.
I add an advenced rule in the preferences/column_color menu with template value like:

format_date(today(), 'yyyy-MM-dd') == format_date({timestamp}, 'yyyy-MM-dd')

I have also tried with _today as:

format_date(_today, 'yyyy-MM-dd') == format_date({timestamp}, 'yyyy-MM-dd')

but I must be committing some kind of mistake because these rules do nothing to my today's books.
Could you please tell me what template value should I use?

Version:
Calibre 0.9.3
Language: Spanish
Windows XP

Thanks a lot,
Odinokij
