SecureStack C3, and lower
SecureStack C2, firmware 3.00.50 and higher
SecureStack B3, firmware through 

Enabled Routing.
Enabled SNTP.
Did not add a host IP address. 

SNTP does not start upon initial switch boot-up, even though configured properly (5571).
SNTP has a status of "Other" with server status as "Active".
SNTP is not polling. 

By design, Network Time Protocol will not function with a zero-value host IP address. Even if it has a routed interface that can ping the SNTP server, it will not poll the server until the host IP address is configured.

For the C3 and B3; upgrade to firmware or higher, and then specify the existing router loopback address or an existing local routed interface as the "SNTP interface" (i.e. 'set sntp interface {loopback loop-ID | vlan vlan-ID}').
For the C2, no change in the stated functionality is expected, due to hardware constraints. 

Pre-upgrade workaround:
Assign an IP address to the switch host, using the 'set ip address...' command (5573).
This does not have to be a valid IP address - just other than Even if the IP address is not reachable on your LAN, the SNTP polling will begin through a routed interface.
