If the unixtime parameter is specified, this application says that date and time. Otherwise, it says the current date and time. If a timezone is specified, the date and time is calculated according to that time zone. Otherwise, the time zone setting of the Asterisk server is used. If the format parameter is specified, the date and time will be said according to that format. (See the sample voicemail.conf file for more information on the date and time format.)
