See attached screenshot for the problem: mb-panel clock gets the time right
(20:29), but the jana clock doesn't (19:29)

I just realized that if DST would be the problem jana would have said '21:29',
not '19:39', so it is merely a timezone problem.

comment:4 Changed 11 years ago by chris@…

Where is the timezone set, so I can add it to the timezone detection function?
libjana respects DST and timezones on the desktop, either through the Evolution
timezone key, through the debian timezone file or the SuSE/Redhat timezone
configuration files, or finally through libc.

comment:5 Changed 11 years ago by koen@…

the timezone is set by making a symlink from
/usr/share/zoneinfo/<continent>/<city> to /etc/localtime.

I suspect jana is missing a tzset() or localtime(), since the matchbox clock and
'date' are picking it up correctly.

comment:6 Changed 11 years ago by chris@…

That isn't how jana gets the time unfortunately, but I'll add a check for
/etc/localtime too tomorrow, that should fix this - I assume that /etc/timezone
isn't there?

comment:7 Changed 11 years ago by chris@…

This should be fixed in r666 (oooh..):

  • libjana-ecal/jana-ecal-utils.c: (jana_ecal_utils_guess_location): Check /etc/localtime symlink if it exists; also verify that whatever timezone returned has a matching built-in ecal timezone

koen, could you verify that this is fixed for you? If it isn't, what timezone do
you have set? I'll investigate further if necessary.

before I test:

root@fic-gta01:/etc$ ls -la /etc/localtime /etc/time*
lrwxrwxrwx 1 root root 36 Oct 3 11:48 /etc/localtime ->
-rw-r--r-- 1 root root 13 Oct 28 11:40 /etc/timestamp

root@fic-gta01:/etc$ ipkg list_installed | grep tzda
tzdata - 2007e-r0 - Timezone data
tzdata-europe - 2007e-r0 - Timezone data

I have correct timezone setted (Europe/Warsaw? - pidgin, matchbox clock, date command and many others shows good time), but openmoko-today always shows me -1 hour (now it's 16:22, but om-today shows 15:22)

root@om-gta02:~# opkg list_installed | grep tzdata
tzdata - 2007k-r3.01 -
