Clocks and Time-keeping
Most computers, mobile devices and tablets will synchronize time automatically via internet using NTP servers or by other means. Pixilab Player kiosks must be configured to use a NTP server to keep the computer clock on time. See this section for details.
Hardware RTC clocks will drift away substantially over time if it does not get sync from the internet.
In the case of a offline installation with no or very limited access to the internet there are still methods to get perfect syncronised time in the system. Setup a dedicated hardware NTP server on the local network that synchronises its built-in clock via radio or GPS. Even without any means to synchronise such device to a reference clock it has a high-quality temperature compensated machine clock that outperforms any PC clock in terms of stability and can easily be manually maintained from a web browser or the front panel.
We have two application notes available using two different method to show time.
The animated wall clock will work even if the Player device is not correct or synchronized as it is fetching the time from a script property the server once every hour to keep the clock on time. This assumes that the server time is maintained manually or automatically.
The world clock example requires that the Player device is configured to maintain its own local clock.
:!:Both Android and iOS devices are designed for constant internet access and generally there are no configuration settings to get the time from a local server. In this scenario it may be most straight forward to use the method in The animated wall clock.
It may be possible to use a DNS server entry they direct any request to a local NTP server. Wireshark may be the tool to find out what NTP server a particular device uses.
