break(date): remove support for 'long', 'longtime' date formats and 'z' flag

The support for the 'z' formatting flag was removed becase the timezone
info can't be retrieved from the browser apis (except for en-US locale
on some but not all browsers). For this reason we don't want to support
this flag at all.

Related to this, since the 'long' and 'longtime' datetime formats require
the 'z' flag in the formatting string, we are removing support for this
format as well.
