actually it ought to read it, maybe not everytime but at least once every 10-15
minutes (think of a server daemon - like CAP aufs etc that runs for potentially
months or years at a time)) just in case the timezone changed (ie those two
times twice a year when the daylight-saving changes)

yes ... this is a bug and has been reported to "the proper authorities" along
with the fix ...
