Thank you for both MChronos and mephemeris. I installed them both through the repositories without difficulty.
I'm a seaman and still consider myself a navigator, even though we just read GPSs most of the time. I like the precise information and the different ways to show it.
I'm looking now for a way to suppress the display of the Season bar and show just the Sun and Moon bars.
I find the applet pretty slow; I'm using an N800 with Diablo. But I'm also displaying Clock, FM Radio, HomeIP, Internet Radio, and Internet search.
I edited my mchronos.ini, and noticed the entire ~/.mchronos directory is owned by the root user and group. Rather than changing the permissions to world-read and world-write, I changed the ownership of the directory and everything in it. Perhaps you could have the files installed that way. That's a better solution than chmod 777.
When I rebooted the N800 mchronos came up with the Sun and Season bars, their text data, and the mode toggle buttons, but no Moon bar or data. I disabled the applet and re-enabled it, and the display came up normally.
