Package: groff Version: 1.23.0-2 $ echo "" | groff -T pdf | grep -F -a Date 5 0 obj << /CreationDate (D:20240426202138+01'+00') /ModDate (D:20240426202138+01'+00') $ echo "" | groff -T pdf | grep -F -a Date 5 0 obj << /CreationDate (D:20240426202145+01'+00') /ModDate (D:20240426202145+01'+00') $ echo "" | groff -T pdf | grep -F -a Date 5 0 obj << /CreationDate (D:20240426202150+02'+00') /ModDate (D:20240426202150+02'+00')
Note the '+00' instead of '00' at the end of the date string. Also note that the first two attempts resulted in a timezone offset of +01:00, but the last one had a timezone offset of +02:00 (the last one is correct). A non-Debian groff 1.23 does not exhibit those issues: ~> echo "" | groff -Tpdf | grep -F -a Date 5 0 obj << /CreationDate (D:20240426202132+02'00') /ModDate (D:20240426202132+02'00') ~> echo "" | groff -Tpdf | grep -F -a Date 5 0 obj << /CreationDate (D:20240426202142+02'00') /ModDate (D:20240426202142+02'00') ~> echo "" | groff -Tpdf | grep -F -a Date 5 0 obj << /CreationDate (D:20240426202151+02'00') /ModDate (D:20240426202151+02'00') see also https://lists.gnu.org/archive/html/groff/2024-04/msg00026.html for a possible patch
