- Following the feature navigator : https://cfnng.cisco.com/ , it probably can. You are however better off by configuring an ntp service besides the switching environment and let the switches use that.

No, the 9300 alone can not act as a "trustworthy" NTP server or NTP master.

All Cisco switches and routers still require to synchronize their NTP clocks to a Stratum 1 or 2.

A Raspberry Pi is a very cheap computing device which is a suitable platform to be a Stratum-1 NTP server.

Try

Cisco 9300 switch can act as NTP master clock

First, make sure your switch is getting it's time from a reliable source (lowest stratum possible)

Configure your switch to act as master clock and set a stratum level for it

ntp master 2

Make sure your switch has an interface configured with an ip address reachable by your intended NTP clients
