Numeric operations are also covered in 
Format of Dates and Times in an Expression
When configuring an advanced expression in a policy that works with dates and 
times, for example, the NetScaler system time or a date in an SSL certificate, you 
specify a time format as follows:
GMT|LOCAL [yyyy] [month] [d] [h] [m] [s]
Where:
yyyy
 is a four-digit year after 
GMT 
or LOCAL.
month
 is a three-character abbreviation for the month, for example, Jan, 
Dec
.
d
 is a day of the week or an integer for the date.
You cannot specify the day as Monday, Tuesday, and so on. You specify 
either an integer for a specific day of the month, or you specify a date as the 
first, second, third weekday of the month, and so on. Following are 
examples of specifying a day of the week: 
Sun_1
 is the first Sunday of the month.
Sun_3
 is the third Sunday of the month.
Wed_3
 is the third Wednesday of the month. 
30
 is an example of an exact date in a month.
h
 is the hour, for example, 10h.
s
 is the number of seconds, for example, 
30
s.
The following example expression is TRUE if the time is between10:00 a.m. and 
5:30 p.m. local time, as determined from the time zone setting on the NetScaler. 
(Note that not all local time zones are supported.):
http.req.date.between(GMT 2008 Jan, GMT 2009 Jan) 
The following example expression is TRUE for March and all months that follow 
March in the calendar year, based on GMT time:
sys.time.ge(GMT 2008 Mar)
