I tried to manually set the time so that the ntp server and the switch will have almost identical time, and btw NTP Server is a firewall, IP of the switch is allowed, and im actually seeing logs on the firewall side(watchguard) that it is trying to sync w/ the ntp server

Not sure yet. But if you can downgrade to a more stable IOS, like 15.0(2)SE4, and NTP works then ...

hi, i allowed that access by adding the IP Address of my core swc to the NTP firewall rule therefore allowing it
