# 
# Can be used in a call menu prompt to play a date string as defined by the settings below
#
# ; Below are the parameters needed for the script to be run properly
# ; the "SAY DATETIME" parameters for what to say separated by three dashes
# ; 1. offset from current epoch in seconds, positive or negative 
# ;		1 hour is 3600
# ;		1 day is 86400
# ;		1 week is 604800
# ;		30 days is 2592000
# ;		1 year is 31536000
# ; 2. format of the date to say, i.e. "ABdY":
# ; 	A: Day of the week
# ; 	B: Month (Full Text)
# ; 	m: Month (Numeric)
# ; 	d: Day of the month
# ; 	Y: Year
# ; 	I: Hour (12-hour format)
# ; 	H: Hour (24-hour format)
# ; 	M: Minutes
# ; 	P: AM/PM
# ; 	Q: Shorthand for Today, Yesterday or ABdY
# ; 	R: Shorthand for HM
# ; 	S: Seconds
# ; 	T: Timezone
#
# ;inbound calls check calltime: 
# ;   (this example is for yesterday and says "Monday March 25th 2013")
