[svn-r26413] Merge of r26276 from trunk.
Cleans up time functions in the autotools input files. - Lumps all the time functionality together in configure.ac. This was previously more spread out due to Solaris issues with the ordering of certain checks. - Removes processing that handles __tm_gmtoff members of struct tm. (libc-4) - Removes BSDgettimeofday(). (IRIX 5.3) - Removes timezone struct processing in gettimeofday(). (considered harmful) Fixes: HDFFV-9083 and HDFFV-9085 Tested on: h5committest OS X (quail) Solaris (emu)

+ - Removed obsolete time functionality from configure and C library
+
+ The library contained some residual functionality from obsolete
+ time zone handling code. This has been removed and the configure
+ checks for the time functions have been cleaned up.
+
+ * Lumped all the time functionality together in configure.ac.
+ This was previously more spread out due to Solaris issues
+ with the ordering of certain checks.
+
+ * Removes processing that handles __tm_gmtoff members of struct
+ tm. (libc-4)
+
+ * Removes BSDgettimeofday(). (IRIX 5.3)
+
+ * Removes timezone struct handling in gettimeofday(). (considered
+ harmful)
+
+ Note that the HDF5 library stores timestamps in a platform-independent
+ manner, so old files can still be read. This only affects convering
+ system time to HDF5 timestamps.
+
+ The library currently uses the tm_gmtoff member of the tm struct
+ (preferred, if available) or the timezone global variable to
+ construct HDF5 timestamps.
