Doesn't seem to work on MacOS X either. But you can use %e for the day of the month:


Code Select
(date (date-value) 0 "%a %e %b %Y")
;-> "Sat  3 Oct 2009"

It works on Win32 using "%#d" and on FreeBSD and UBUNTU Linux using "%-d" as written in the manual. On OpenBSD, SunOS/Solaris and Mac OS X use the "%e" as shown by cormullion.



newLISP internally uses the C function strftime() for formatting dates. The format characters offered on different platforms differ. Use "man strftime" on Unix platforms to consult the man page for your implementation.



The newLISP manual only shows formatting characters found on all platforms. There are many more format characters and platform/locale specific extensions. Here a link to a typical Unix man page:

I will add the "%e" form to the manual as it seems to be popular on Unixes.
