AFAIK /etc/localtime points to glibc timezone file ($TZ). When clock is set to GMT,
but system (through localtime()) needs to know exact local time -- glibc library opens
that file to get the idea what offset needs to be applied to GMT time to have exact
local time as a result. This happens with every software on such configured system (i
just tried strace with /bin/date and /usr/bin/cal just to be sure) -- IMHO nothing to
worry about in terms of performance.
