Re: Setting the time
Hi, In a school deployment, it is desirable that all of the XOs have the same time. This time should be synchronized with/by the school server (even if the school server is wrong). It is not reasonable to base this capability on access to the internet. Casio sells 'atomic' watches that synchronize to Ft. Collins by radio. Neat, but how does this work in Rwanda?

Re: Setting the time
If anti-theft is used with delegated leases (so the school server can give leases for a few weeks at a time), the XOs will trust a signed timestamp provided from the school server. However olpc-update-query will only reset the XO's clock if it is off by more than a day. According to a comment in the code this is done to avoid messing with NTP, except our OS builds don't currently have NTP in them. School servers run NTP servers which NTP clients can connect to. These are not currently configured to support running without an external NTP source, although they can be configured to do so. If a locally accurate clock at the XS site is required and Internet is not available, NTP can use a cheap USB or serial GPS unit as a time source. Running gpsd or similar may be required depending on the GPS's supported protocol(s). In any case if OLPC or Sugarlabs wants to formally integrate NTP services into our products, we should be polite and ask ntp.pool.org if we need our own vendor subdomain. These allow the NTP pool to shut off misbehaving clients without affecting other users, and Fedora and CentOS already have their own.

It used to do that on shutdown as part of /etc/rc.d/init.d/halt and friends, but I think it got dropped as part of the switch to systemd. grep hwclock /etc -r doesn't find anything.

Re: Setting the time
In a school deployment, it is desirable that all of the XOs have the same time. This time should be synchronized with/by the school server (even if the school server is wrong). It is not reasonable to base this capability on access to the internet. How closely do you need them to be synchronized? 1 second? 1 microsecond? 1 minute? It should be reasonably easy to setup ntpd on the school server and get the XOs to set their clocks when booted. You may want/need a cron job to set the time occasionally. Casio sells 'atomic' watches that synchronize to Ft. Collins by radio. Neat, but how does this work in Rwanda? WWVB runs at 60 KHz. There are several similar systems in other countries. I don't think any of them make it to Africa. GPS does. You can get USB GPS receivers for under $50. The SiRF chip is the most popular in the low cost units. It's crappy if you need ms level timing, but good enough if all you need is 1 second. -- These are my opinions.

Re: [Server-devel] registering an xo for second time
If the OS/Sugar build is new enough, the Register option never disappears from the Right click menu of the XO character in the home view, and re-registration is possible with no editing required. The Register option only appears on the screen which has the application Circle/Spiral present, and not in the Network view or Friends view. Given shutdown restart appear on all three screens, this is potentially a bug. I believe 11.3.0 supports re-registration; 11.3.1 12.1.0 definitely do. The exact ticket which enabled this behavior currently is eluding me.
