as suggested by reneeb
Fixed syntax issue.
Fixed POD.
Removed useless TimeObject.
Added missing release date for 3.2.10.
Removed use of Time module.
Added test for Pod::Simple version.
Fixed Undefined subroutine message.
Revert "Removed useless TimeObject."

This reverts commit 9bcfb3c1cf639fa81da732fbf8cac6eb480b0033.
Wile the MailAccount object does not require the TimeObject and
tests run fine, the backends DO need it to be able to create
the PostMaster object.
Added cache for dashboard filters.
Small translation improvement.
Fix cache key due to hash randomization.

Calling 'keys' on a hash does not guarantee to return the keys in
any given order. The next time you call 'keys', even on the same
hash, the order *can* be different. Because you use it here for the
constructing the cache key, this will result in a cache miss.

Also, starting Perl 5.18, the next time you perform 'keys' on the
same hash, it's GUARANTEED that the result will be different!
