Looks like a simple oversight or bug in RHEL 6 that was fixed for 7.
The latter is correct for UK standard usage. CentOS just follows RHEL.

It is defined in the file /usr/share/i18n/locales/en_GB

CentOS 6 has:

date_fmt    "<U0025><U0061><U0020><U0025><U0062><U0020><U0025><U0065>/

which translates to "%a %b %e", e.g. "Thu Nov 15"

CentOS 7 has:

date_fmt    "<U0025><U0061><U0020><U0025><U0065><U0020><U0025><U0062>/

which translates to "%a %e %b", e.g. "Thu 15 Nov"
