Checked MATE Clock on FreeBSD and Fedora (where I run MATE > Desktop) and those display correctly. to fix that issue, mate-panel changed from one strftime extension (%l, supported by OpenBSD but not musl libc) to another (%_I, glibc extension, supported by musl libc, FreeBSD and reportedly AIX, Solaris) the %_ extension is from a set of three modifiers which specify padding behaviour instead of the default for the following format character: %0K - like %K but pad numbers with zeros %_K - like %K but pad numbers with spaces %-K - like %K but do not pad numbers patching this in mate-panel is a pain because the strftime strings are used as translated strings (i.e. changing to the common local format where available) so a bunch of .po files would need patches. taking a cue from libc's "support" for %E/%O (C99 locale modifiers which are recognised but ignored) here's a diff to ignore the modifiers so at least we'd get something sensible printed in these cases. (if testing with date(1) note that it's statically linked). would this or something like it make sense?
