How do you get that from this text: ntp_adjtime () The ntp_adjtime() library function (described in the NTP "Kernel Appli‐ cation Program API", KAPI) is a more portable interface for performing the same task as adjtimex(). Other than the following points, it is identical to adjtime(): * The constants used in modes are prefixed with "MOD_" rather than "ADJ_", and have the same suffixes (thus, MOD_OFFSET, MOD_FREQUENCY, and so on), other than the exceptions noted in the following points. * MOD_CLKA is the synonym for ADJ_OFFSET_SINGLESHOT. * MOD_CLKB is the synonym for ADJ_TICK. * The is no synonym for ADJ_OFFSET_SS_READ, which is not described in the KAPI. > > What system has adjtimex(2) and not ntp_adjtime(2)? > > None that I know of. I doubt any such exost. because if you have > adjtimex(2) you can implement ntp_adjtime(2) with it. Right, they are equivalant, so no big reason to change, except the man page requests it.
