TL;DR
The gmttime in standard libray on windows platform cannot represent the date before Unix Epoch.
http://msdn.microsoft.com/en-us/library/0z9czt0w(v=vs.100).aspx
"""
Both the 32-bit and 64-bit versions of gmtime, mktime, mkgmtime, and localtime all use one tm structure per thread for the conversion.
Each call to one of these functions destroys the result of any previous call.
If timer represents a date before midnight, January 1, 1970, gmtime returns NULL. There is no error return.
_gmtime64, which uses the __time64_t structure, enables dates to be expressed up through 23:59:59, December 31, 3000, UTC,
whereas _gmtime32 only represent dates through 03:14:07 January 19, 2038, UTC.
Midnight, January 1, 1970, is the lower bound of the date range for both of these functions.
gmtime is an inline function that evaluates to _gmtime64 and time_t is equivalent to __time64_t unless _USE_32BIT_TIME_T is defined.
"""
An alternative could be boost date_time libraray.
```
#include <boost/date_time/posix_time/posix_time.hpp>
using namespace boost::posix_time;
ptime pt = from_time_t(t);
struct tm d = to_tm(pt);
```
Howerver, boost date_time library still has year 2038 problem which is still not fixed.
https://svn.boost.org/trac/boost/ticket/4543
One reason is that the library converts the 64-bit`time_t t` into `seconds` type to get posix time.
But boost uses `long` to represent `seconds`, which is 4 bytes on windows platform,
http://msdn.microsoft.com/en-us/library/s3f49ktz.aspx
We eventually choose the third-party MIT-licensed library written with ANSI C.
