Time functions
Use the built-in time functions to examine system time. These functions use the time or
interval parameters.
The time parameter can include the following options:
 Day of week[Sun, Mon, Tue, Wed, Thu, Fri, or Sat]
 Month[Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, or Dec]
 Date[1 to 31]
 Year[1997 to 2100]
 Hour of day[00: to 23:]
 Minute[:00 to :59]
 Second[:00 to :59]
It does not matter in what order options are listed. You can include any or all of these
options; the more you include, the more specific the time becomes.
Example 1: Specific time parameters
The following all represent the same date and time, and are valid time parameters:
 "mon aug 22 2005 17:00"
 "mon aug 22 2005 17: :00"
This function Returns
TIME(“time”) 1 (true) if the time specified is the current time.
BEFORE_TIME(“time”) 1 (true) if the expression is evaluated before the
specified time.
AFTER_TIME(“time”) 1 (true) if the expression is evaluated after the
specified time.
INTERVAL(“interval”) 1 (true) if the specified time interval has elapsed—
the interval timer starts running when an event file
starts running.
The time and interval parameters must be enclosed in quotes.
