FileException if it fails to read from disk.PosixTimeZone.getInstalledTZNames
string[] getInstalledTZNames(string subName = "", string tzDatabaseDir = getDefaultTZDatabaseDir()) @safeReturns a list of the names of the time zones installed on the system.

subName | The first part of the desired time zones. |
tzDatabaseDir | The directory where the TZ Database files are located. |
