The current DateViewHelper has no support for localized dates so I created a version that uses strftime() to render strings.
Additionally it supports UNIX-timestamps, dates that are understood by strtotime() (i.e. "2010-07-27") and DateTime-objects.
And you can also calculate dates relative to the given one. This way you can add days, weeks, months or whatsoever or get the first day of a week, a month or a year.
Keen on hearing your opinion.
