I realize I may have the only Epygi IPBX in Samoa (the old Western Samoa). Our capital Apia is not in the time zone list and I have used Tonga's capital Nuku'alofa. We have recently moved the dateline (UTC +13:00) and now also have daylight savings.

Rather than having the time zones hard coded into firmware (which I suspect they are), could we have a way of editing them ourselves.
