This may sound like a really dense question but I am looking for a list of standard timezones that windows recognises using the putenv("TZ") function. I have all the timezone definitions for Linux which are stored in a database and called to display the time in different time zones. However I have moved the site to a windows IIS server and require the Abbreviations that windows understands ie: GMT0BST etc. Does anyone know where I can get this information?
