示例20: ParseTIMESTAMP3164

/**
 * Parse a TIMESTAMP-3164. The pTime parameter
 * is guranteed to be updated only if a new valid timestamp
 * could be obtained (restriction added 2008-09-16 by rgerhards). This
 * also means the caller *must* provide a valid (probably current) 
 * timstamp in pTime when calling this function. a 3164 timestamp contains
 * only partial information and only that partial information is updated.
 * So the "output timestamp" is a valid timestamp only if the "input
 * timestamp" was valid, too. The is actually an optimization, as it
 * permits us to use a pre-aquired timestamp and thus avoids to do
 * a (costly) time() call. Thanks to David Lang for insisting on
 * time() call reduction ;).
 * This method now also checks the maximum string length it is passed.
 * If a *valid* timestamp is found, the string length is decremented
 * by the number of characters processed. If it is not a valid timestamp,
 * the length is kept unmodified. -- rgerhards, 2009-09-23
