Comment 4 for bug 993161

Confirmed, the issue is coming from indicator-datetime/src/utils.c's generate_format_string_full() code, which uses this as a format string for strftime: "%a %b %e"

Where:

       %a The abbreviated weekday name according to the current locale.
       %b The abbreviated month name according to the current locale.
       %e The day of the month as a decimal number, but a leading zero is replaced by a space. (SU)

which is fine for some locales, but probably %b and %e should be reversed in some locales.

IMO this would best be handled by the translation replacing the default string with a more appropriate one.
