We have recently deployed Zimba Open Source in a company. They are mostly pleased, however, there is a problem. Due to broken IT policy, each OS is configured with different Regional settings. Also, users are allowed to install Firefox and Opera in addition to IE and they seldom remember to configure proper locale, as almost no other site except Zimbra is affected by this. This wreaks havoc with Zimbra date&calendar mgmt. Fixing locale on each computer is not feasible.
Please instruct, which source file / class is used to detect locale from web browser, so I can hardcode my prefered locale for all users? Hopefully, I will later create a table of exceptions.
Thanks in advance.
