My setup at home is:

laptop is MAC OS, has WIFI connection to Internet.

Board pynqz1 is usb-powered, ethernet cable connected to laptop with static IP.

SSH-ed on the board. Found that the date almost never got corrected.

Hey Rock, With static IP the date can never be corrected as ntpd fetches data from Internet.

Adding iburst directive to ntp servers in /etc/ntp.conf takes time down to 30s - which is expected time. We will work into next image

Time has been updated ~30s after booting up. Needs to be integrated and tested in next image.
