Fix ctime() standard compliance bug
fixes issue2209: ctime() was updated in 0.9.31 to call localtime_r() instead of localtime() to avoid using a static buffer. Unfortunately, this change replaces the static buffer (which is zeroed out on initialization) with an uninitialized local buffer. In the common case, this has no effect. However, with a sufficiently large time_t value, the value returned differs from that returned by asctime(localtime(t)), and thus violates the ANSI/ISO standard. An example input is (on a 64-bit machine): time_t t = 0x7ffffffffff6c600; Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
