HELP
An object that generates the current day,
date, and time and outputs as a constant,
Real value of the number of seconds between
the beginning of the Epoch (defined as
beginning at 0000 hours UTC on January 1, 
0001 AD and now.

USE
Use Time Stamp to generate the current day,
date, and time to document your model, time
stamp data (such as in a file), in alpha
displays, or to label a panel.

The Time Stamp is used for alpha displays
and to document data collection times by
sending the times to a file.  Time Stamp
allows you to know when an object has
operated.

To display this number in a time and date
format, use the Number Formats feature on the
AlphaNumeric or Logging AlphaNumeric objects.

LOCATION
Device ==> Time Stamp

EXAMPLES
Use Time Stamp to indicate when data was
collected.  At the beginning of an
experiment, activate a Time Stamp box, then
send its output in date/time format to the
same file as the experimental data.  Also,
send the Time Stamp output to an alpha
display changing the alpha display to a
date/time format that is useful to you.  Now
you can tell when the experiment started
running.

For a complex experiment, you can measure
the elapsed time running during a graph
execution.  Use two Time Stamp boxes.
Activate the first one at the start of the
experiment and the second one at the point
where you want to measure elapsed time from
the first one.  Subtract the values in the
two boxes and send the result to an alpha
display for the elapsed time value.  The
Timer object is generally more useful for
timing models.

NOTES
The day, date, and time are taken from a call
to the HP-UX system clock.  The output value
is a large number on the order of 62.xxxG.

The output is of type Real.  It can be
used for comparison or mathematical
calculations.

Time Stamp has no input dependencies.
Unless the sequence input pin is connected,
it operates as soon as the model begins to
run.

Time Stamp is different from Date/Time in
that it generates the current date/time when
activated.
