Description:
The tm structure describes the calendar time.
The members of this structure include:
- tm_sec
 
- Seconds after the minute, in the range [0,61], allowing for leap seconds.
 
- tm_min
 
- Minutes after the hour, in the range [0,59].
 
- tm_hour
 
- Hours after midnight, in the range [0,23].

- tm_isdst
 
- Daylight saving time flag.
  This field is positive if daylight saving time is in effect, 0 if daylight saving time isn't in effect,
  and negative if the information isn't available.
 
- tm_gmtoff
 
- (QNX Neutrino extension) The offset from UTC; see
  setlocale().
 
- tm_zone
 
- (QNX Neutrino extension) A pointer to the time zone's name.
  
Note: 
  This pointer could become stale or invalid after the next call to
  
tzset().
