[MM3-users] 12/24 hour clock ?

Hi all

at openSUSE we have recently migrated to mailman3, and we seem to be having a couple of teething issues:

a) hyperkitty and postorius both seem to insist on using a 12 hour clock format, no matter what the user has set. Is there a way of changing it system-wide ?

b) overriding the default set of footers - despite having set the template "list:member:regular:footer" to empty for a specific list, I am still getting the default footers attached.

We are using version 1.3.3.

thanks Per Jessen
