I am beginning to suspect the issue here stems from a difference in
viewpoint on the OP's part about how time is stored/displayed.
I am suspecting that when the OP says "system time" he is
referring/viewing only the outermost shell of the onion (the "date"
command output), and that when he says "system time" he means that he
types "date" into a shell and see's local time printed out by the
"date" command,
Most of the rest of us are discussing this with him using a definition
of "system time" that unwraps several layers of the onion, such that
"system time" and "output of 'date' command" are two very different
items in our minds.
I.e., we are talking about this four layer onion:
hardware clock (inner most layer - set to UTC)
|
|<--read at boot
|
linux "system time" (also set to UTC) (layer 2)
|
|<--read (at least) by glibc time functions
|
glibc time zone handling library code (layer 3)
(performs translation of UTC into localtime)
|
|<--request from 'date' to glibc for "current time"
|
date command (outer shell of onion, layer 4)
And when we talk about "system clock" it is not the output of the
'date' command, but the time value the kernel stores internally, that
is read by the glibc time library functions, and translated into
localtime therein, then handed off to the 'date' command to simply be
formatted for human viewing.
The reason I am beginning to think the OP is viewing just the outer
shell is his continued insistence that his clock is set in local time,
but that he is also using ntpdate to set his system clock. As has been
stated a few times by others, NTP itself knows only UTC. So unbeknowst
to the OP, his system clock (and maybe his hardware clock as well) is
actually set to UTC, But because he see's localtime from the 'date'
command, in his mind his system clock is set to localtime.
