Description
Time zone handling logic in the WebUI is a kludge, coded to parse only "GMT-N" time zone specifications and defaulting to PST, if parsing is not successful (kylin/webapp/app/js/filters/filter.js)
Integrating moment and moment time zone (http://momentjs.com/timezone/docs/) into the product, would allow correct time zone handling.
For the users who happen to reside in the geographical locations that do observe day light savings time, usage of GMT-N format is very inconvenient and info reported by the UI in various places is perplexing.
Needless to say that the GMT moniker itself is long deprecated.
