{zone-data:overview}
This helper calculates the time passed from timestamps to generate a formatted string like "5 days and 4 hours". Applications of this helper are generally seen in "Created 2 weeks ago" or "Last modified 5 minutes ago" type lines.

Units supported are years, months, weeks, days, minutes, seconds. String format is the largest possible unit and if possible the unit below it. If a 1 year and 2 weeks have passed then "1 year" is the output; however, if 1 year, 2 months and 5 days have passed then "1 year and 2 months" is returned. If less than a second have passed then "less than a second" is returned.

Output is automatically translated if possible using Zend_View_Helper_Translate. The translation format is '%d months'. An already completed gettext pot file is located on Zym's demo in the data locale folder.
