as per http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=276248
Changed range for "%S" from 0..61 to 0..60.
SUSv3 says 0..60. I think the manual page probably says
0..61, because that's what SUSv2 said.
(Some other implementations' man pages also say 0..61 --
e.g., Solaris 8 & 9, Tru64 5.1B; FreeBSD 5.1 says 0..60.)
The glibc manual currently says 0..60.
Given that SUSv3 says 0..60, I've changed this the
manual page to also say this:
-The second as a decimal number (range 00 to 61).
+The second as a decimal number (range 00 to 60).
+(The range is up to 60 to allow for occasional leap seconds.)
