Get rid of the trailing new line added by ctime()

Get rid of the trailing new line added by ctime()

From the POSIX documentation of ctime:
	The ctime() function shall convert the time pointed to
	by clock [...] to local time in the form of a string.
	It shall be equivalent to:

        asctime(localtime(clock))

From the POSIX documentation of asctime:
	The asctime() function shall convert the broken-down time
	in the structure pointed to by timeptr into a string in the
	form:

	Sun Sep 16 01:03:52 1973\n\0

We need to get rid of that new line otherwise it appears in the log.

The POSIX documentation goes on:
	These functions are included only for compatibility with older
	implementations. They have undefined behavior if the resulting
	string would be too long, so the use of these functions should
	be discouraged. On implementations that do not detect output
	string length overflow, it is possible to overflow the output
	buffers in such a way as to cause applications to fail, or
	possible system security violations. Also, these functions do
	not support localized date and time formats. To avoid these
	problems, applications should use strftime() to generate
	strings from broken-down times.

Because we have already been using strftime() with gmtime() elsewhere,
using strftime() with locatime() here makes sense.

The i1On mechanisme we currently use to print dates is non-sensical:
we force the format string to "%a, %d %b %Y %H:%M:%S" which might not
make sense in some locales. We shall fix i10n in a different merge
request or commit.
