There has been a discussion on this quite some time ago here:

https://rtems-devel.rtems.narkive.com/EoIm4krA/sleep-time-is-doubled-xilinx-zynq-zedboard

However, the issue has never been fixed. As outlined in the
discussion, this must be f_cpu / 2. Thus as long as the
board has an 33.333MHz osc., and the default pll settings are
used, f_cpu equals 666.7 MHz and this setting becomes 333MHz.
