https://cgit.freedesktop.org/libreoffice/core/tree/i18npool/source/localedata/data/es_ES.xml#n50 In Spanish, these are abbreviations, not acronyms, and thus should be written “a. m.” and “p. m.” instead of “AM” and “PM”. The Spanish language has a uniform, pan-region orthographic norm, so this is applicable to all locales. Please use a no-break space in between. TIA!
Here's the patch: https://gerrit.libreoffice.org/c/core/+/129793 As I indicated in comment: "Since you talked about Spanish locales, should we do the same in source/localedata/data/an_ES.xml ?"
Patch for 7.3 waiting for review here: https://gerrit.libreoffice.org/c/core/+/129843
