Adding OpenLayers.Date utility functions to parse and serialize dates. The date string format parsed complies with ECMA-262 (v5) section 15.9.1.15, derived from the profile of ISO 8601 for date and time on the Internet (http://tools.ietf.org/html/rfc3339). Where available (and functional) the native date.toISOString and Date.parse methods will be used. r=ahocevar (closes #2778)
