Hello to everyone,
I'm new to the list and would like to ask about displaying the upcoming
leap second on a linux workstation.
I use a PC running linux 2.6.24 and the djb clockspeed daemon periodically
synchronized with a couple of different NTP servers. I usually have a
correct reading within ~10ms (I know, it's not atomic time 8-)
I also use the "right/America/Los_Angeles" time zoneinfo file for correct
synchronization with TAI, and installed the new leapsecond.dat file for
2008 in /etc. (and I restarted clockspeed)
I'm on the pacific coast of the US and as such the leapsecond occurs here
just before 4pm.
I've used the date command to set the time of my computer to Dec 31 2008
15:58 PDT and watched as the hour rolled over: No LeapSecond!
It goes from 15:59:59 to 16:00:00
I've been using XDaliClock as the display, which uses the unix localtime()
call to retrieve the time from the system.
I've done quite a bit of scroogling in an attempt to determine how the time
is kept in the kernel and how it makes it's way through to userspace for
applications like date and xdaliclock to access. I didn't determine 8-(
Can anyone advise me as to the feasibility of using this configuration to
display the leapsecond to a crowd of eager viewers at the end of this year?
Thank you so much for your consideration of my noobish question, and for
maintaining an active interest in something just because you like it!
ciao bella...
johnea
