Just to make it clear to everyone interested - also in the future :
1 - 'hwclock --show' : reads by its own the content of '/etc/adjtime'
(if this file does not exist the dafault(*) is localtime) to understand
if the RTC is in UTC or LOCALTIME than it shows, after a conversion if
necessary, the time in localtime.
[...]
If all that I wrote is correct : why the command ' hwclock --show
--localtime' shows me the UTC time and 'hwclock --show --utc' shows me
the localtime ?
That is all very well for some. My Acer Aspire with etch responds to
all hwclock queries with this:
select() to /dev/rtc to wait for clock tick timed out
But it seems to work just the same...
Hi Richard,
I actually don't understand why u picked up two different mails of mine
and joined them :-( . Maybe were u trying to explain what happens to u ?
Anyways, in my situation all the hwclock output finally was right
1- with ' hwclock --show --localtime' I tell the software (with the
"flag" --localtime) that the time in RTC is stored in localtime. So the
RTC time is output without a conversion because it MUST show the
localtime (this is _its mission_). But that information is wrong cause
the time in RTC is stored in in UTC time !
2- with ' hwclock --show --utc' I tell the software (with the "flag"
--utc) that the time in RTC is stored in utc. So the RTC time is output
_with_ a conversion because it MUST show the localtime (this is its
mission). And now the information was right.
So the "flags" that u use on the command line (--localtime, --utc) tell
the software (hwclock) an information that it needs to produce the
output AND NOT what the output will be - because the OUTPUT WILL ALWAYS
BE LOCALTIME - its mission, remember.
I also found on the net a wiki that u can check if your problem is
My Acer Aspire with etch responds to
all hwclock queries with this:
select() to /dev/rtc to wait for clock tick timed out
here it is : http://www.thinkwiki.org/wiki/Problems_with_hwclock
I hope I ve been of help,
cheers
