<p>If you PRINT a VDEF value, you can also print the time associated with it by appending the string
<strong>:strftime</strong> to the format. Note that rrdtool uses the strftime function of your OSs clibrary. This means that
the conversion specifier may vary. Check the manual page if you are uncertain. The following is a list of
conversion specifiers usually supported across the board.</p>
