-date_stamp option is used for two purposes.
One, as a point of reference to the time the regression results were
generated. Two, as a means to uniquely store results that have the same
regression list name (See Figure 1.1: Main Report Web Page). The RRT default is to generate
a date stamp of the form MM_DD_YYYY-hh.mm at the time the tool is
called. However, if one would like to use a different unique labeling
system one can override this behavior by supplying one’s own date stamp.
Note: since the date stamp is used in creating files and directories it
must contain only those characters that are acceptable for such.
