[nsp] ntp on 11.2?

[Furnish, Trever G]

O kind and generous nsp readers,

Am I nuts or should the ntp configuration commands be available in ios 11.2?
Specificly they seem to be missing in a switch I have running this:
IOS (tm) C2900XL Software (C2900XL-HS-M), Version 11.2(8.10)SA6, MAINTENANCE
INTERIM SOFTWARE

misw2#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
misw2(config)#ntp?
% Unrecognized command

The documentation seems to suggest they should be there...

Anyone mind sharing a release number for 11.2 later than my current release
that they can vouch for as having ntp commands available?
