Trying to get NTP to work on 908E:
1) Enabled DNS Lookup
2) Configured default gateway
3) Configured NTP Master 4 (stratum 4)
4) Configured ntp server time.nist.gov
908E-R1#sho run | inc ntp
no ip sntp server
ntp master 4
ntp server time.nist.gov
908E-R1#sho ntp status
Clock is synchronized, stratum 5, reference is LOCAL
reference time is 7C558180.0 (01:28:16 EST Thu Feb 7 2036)
clock offset is 0.00 msec, root delay is 0.00 msec, precision is 2**11
root dispersion is 10.52 msec, peer dispersion is 0.52 msec
clock jitter is 0.00 msec, clock drift compensation is 0.000000e+00 s/s
clock stability is 0.000000e+00 s/s
908E-R1#sho ntp asso
Address ref ID st when poll reach delay offset disp

I should have mentioned that I already tried that.
Apparently NTP and SNTP can't be enabled at the same time? When I enable SNTP, none of the NTP commands work (like "sho ntp status" or "sho ntp asso").
908E-R1(config)#sntp server time.nist.gov version 3
You must first disable NTP before configuring SNTP.
That is correct remove the ntp settings and just add.
sntp server time.nist.gov version 3
You may also want to make sure you can ping time.nist.gov from the 908e.
This will rule out DNS or routing issues.
