The icodd daemon performs routine
iCOD software tasks at noon and midnight on a daily basis. An iCOD
partition’s local timezone setting affects what timezone
the icodd daemon uses for the timing of
noon and midnight.
Because the icodd daemon is started
by init, the /etc/default/tz file needs to contain the desired timezone specification.
By default, the timezone is set to EST5EDT. You
can specify the timezone the icodd daemon
uses to interpret noon and midnight by modifying the entry in the /etc/default/tz file.
