+     "The @code{datetime2} package provides commands for formatting dates, times
+and time zones and redefines @code{\\today} to use the same formatting style.
+In addition to @code{\\today}, you can also use
+@code{\\DTMcurrenttime} (current time) or @code{\\DTMnow} (current date and
+time).  Dates and times can be saved for later use.  The accompanying
+@code{datetime2-calc} package can be used to convert date-times to UTC+00:00.
+Language and regional support is provided by independently maintained and
+installed modules.  The @code{datetime2-calc} package uses the
+@code{pgfcalendar} package (part of the PGF/TikZ bundle).  This package
+replaces @code{datetime.sty} which is now obsolete.")
