POSIX has standardized %j to mean the count of days within a Gregorian year, and NOT the astronomical Julian date. http://pubs.opengroup.org/onlinepubs/9699919799/toc.htm We are reluctant to burn %o without it being required by POSIX, because strftime letters are already sparse; this is particularly true of burning a letter to be a synonym to an already standardized letter. The proposal in the thread mentioned above would be to add a %J as the Astronomical Julian date, if there proves to be enough demand, but so far, no one has expressed enough interest to actually write the patch. Therefore, I'm closing this as not a bug, although you can feel free to add further replies to the thread. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
