for Puppy 1.0.5rc, my timezone seems to be correct if /etc/TZ is EST5EDT and /etc/localtime is symlinked to GMT+4

i will probably have to change the timezone to +5 in October

EST5EDT is definitely correct for my timezone
because it's daylight-saving time, it is using the EDT part, so date prints EDT as my timezone ... the letters are not important, the offset number is important ... when it uses EDT it is using an offset of +4 ... in other words, EST5EDT during daylight saving time is the same as UTC+4 ... EST5EDT during standard time is the same as UTC+5 ... the thing about EST5EDT is it should automatically change the time by 1 hour when daylight saving time ends in October

time stuff can get awfully complicated and confusing ... partly because there are so many zones with different (arbitrary and politically created rules)

another thing that is confusing is that the time displayed will change if you change any of the time configurations ... for example, change TZ, the symlink to localtime, the hardware clock setting, the UTC variable, and they will all change the clock display

using UTC=1 is easier ... but if you dual-boot Windows, it wants the hardware clock to be set to local time ... and it will usually automatically reset time that the hardware clock is set to for daylight saving time ... so Linux usually does not try to change the hardware clock setting too, or it would cause problems ... if you dual boot Linux and Windows, then Windows should probably reset the hardware clock for daylight savings ... if you run only Linux, then you will probably need to reset the time zone twice a year

rdate seems to work properly only if you set the timezone correctly ... it's working properly now on my machine with TZ=EST5EDT and localtime symlinked to GMT+4 ... Tor also seems happy ... it prints error messages if your clock is not set properly

one thing that i am certain of ... EST5EDT is the correct TZ for my timezone ... so that makes it easier to get the other setttings right

UTC=1 is a lot easier ... you just set the hardware clock to UTC and set TZ to display the correct local time ... but Windows doesn't like UTC

it's not rocket science, but it's complicated enough ... where's the aspirins?

Edoc,

i think the dates on files are set according the how the kernel clock is configured, which is different from the system clock and from the hardware clock ... apparently, the kernel clock is set by hwclock when it sets the system clock from the hardware clock

all i know, is that some programs are unhappy with the way Puppy's Time Zone wizard sets things, but they seem to be relatively happy if you reverse the sign of the offset ... i've tested it for my time zone and few other time zones i'm familar with and it seems to work ok with all of them

i'm not totally sure how the daylight saving shift works with Puppy ... i think if you use local time, the system is assuming you are dual-booting with Windows and that Windows is going to reset the hardware clock by 1 hour, and behaves accordingly

as far as the forum goes, i think the forum server's clock is about 20 minutes fast ... the time right now is
UTC - Friday, 23 September 2005, 02:36:14
which is my local time:
EDT - Thursday, 22 September 2005, 22:36:14
(i think the server is set to EDT time too)

that is, about 10:36 pm

by the way, the forum server seems to be in Edmonton, Alberta, Canada

I updated the dotpup.
The cancel-button works now.

the existing file can be replaced with this code, if you don't want to install the dotpup (this is for Barry for Puppy 1.0.6 mainly):

Hello! Just installed the program. Works great, thanks very much!

Wow, there's blast from the past!

Into which version of Puppy did you install it, please?

I am observing clock problems 2 years after this thread (in 3.01), so the conflict between the hwclock and the one displayed on the desktop (and the one used by apps like Firefox) remains unresolved - at least unresolved as a default part of the distro.

edoc,
you might have to set the timezone in the desktop-menu.

On my Puppy, "Berlin" (which should be correct) set a wrong zone, so I use "-1" instead, if I remember well.
That works well then.

My time zone is fine, I remember that dance from before.

What is happening on two of our three Puppy Linux computers is that the hardware clock must be losing time and dragging the software clock down with it.

I thought Puppy had added an app to the package that automatically sync'd the clocks with a standard.

I am not sure when 3.02 and 4.xx/Dingo will be released but hopefully both will address this.

Meanwhile, is there an app for this for 3.01?

I got so frustrated with this issue, and trying so many variety of "fixes" that didn't work that my final solution to the problem was this:

Seeing that I have 3 hard drive installs and the time all works fine in those between hwclock/swclock I chose my Linux Mint to repair from. So I wiped everything dealing with "time" out of "/etc" and then likewise in "/usr/share/zoneinfo" I believe it was---and then just brought it all over from Linux Mint into my Puppy 3.0.1 frugal install.

(Sidenote: This is NOT a procedure I'd recommend though to anyone else unless they're willing to take the chance of losing data and messing up! Caveat Emptor!)

It's worked a treat and I've never had to fiddle with resetting from the GUIs or anything since. But you can tell I was pretty annoyed if I was willing to risk destroying that fine Pup I'd built up with all of the goodies found here!

Amicalement,

Perhaps the wonderful Puppy developers will take a look at what you have done and find a long-term solution for this to build into every new release?

just download the set time package and it works, great
you will have to download dot pup handler through set up - puppy manager first, then you will be able to install the set time package.
I don't know why my clock changed all of a sudden I've not done anything for it too?
