[svn] * src/util.c: localTimeDiff() cached its value and recalculated it every hour of clock time, regardless of the time the calculated was based on. This is potentially dangerous at daylight saving changes. So instead use the cached last result only when the new request is to be based on a time in the same hour as the cached result. * src/util.c: Replace the alternate Utl_mktimeGMT() implementation used when timegm() is not available. The previous version, as suggested by the glibc timegm() man page, used setenv() and unsetenv() for changing the environment. These aren't POSIX function, and the POSIX putenv() (a) is tricky to manage if the same var is being constantly update and memory isn't to leak, and (b) provides no way to remove an environment entry. So change to an implementation Wget uses. This should compile on not glibc systems - the previous version failed to build on Solaris.
