Move formatDateISOLocal(epoch, timezone) function (and also helper timezoneOffset(timezoneInfo) function it requires) from common-lib.js to datetime.js Add new functions: * localTimezoneOffset - to get browser timezone offset in seconds * localTimezoneInfo - to get browser timezone in '(+|-)HHMM' format * formatTimezoneInfo - turn offset in hours and minutes into '(+|-)HHMM' * parseRFC2822Date - to parse RFC-2822 dates that gitweb uses into epoch * formatDateRFC2882 - like formatDateISOLocal, only RFC-2822 format All those functions are meant to be used in future commit 'gitweb: javascript ability to adjust time based on timezone' An alternative would be to use e.g. Datejs (http://www.datejs.com) library, or JavaScript framework that has date formatting (perhaps as a plugin). While at it escape '-' in character class inside tzRe regexp, as recommended by JSLint (http://www.jslint.com).
