In my ubuntu 12.04

#ntpd --version
ntpd 4.2.8p6@1.3265-o Wed Mar  2 06:23:51 UTC 2016 (5)

in the above "(5)" represents what?

1

The date after the version number stands for the time when the version was compiled.

My guess is that the (5) has something to do with the Coordinated Universal Time (UTC) value. Maybe the time difference to UTC, in this case +5 hours? So far I couldn't find a document for that.

Seems like the number (5) stands for the times the makefile was executed (thx @ Sharath Manchala).


The version style is the following, just for proving my guess about the UTC date.

NTP uses A.B.C - style release numbers.

At the moment:

 A is 4, for ntp V4.
 B is the major release number.
 C is the minor release number.  Even numbers are 'stable' releases and
 odd numbers are "development" releases.

Following the release number may be the letter 'p' followed by a number.
This indicates a point (or patch) release.

Release candidates have -RC in the release number.

Here are some recent versions numbers as an example:

 4.2.2      A production release (from the ntp-stable repository)
 4.2.2p2    A production release (from the ntp-stable repository)
 4.2.3p12   A development release
 4.2.3p15-rc1   A release candidate for 4.2.4
