Cocos2DX sdk have any function to convert from string representation to seconds?

Question

Thanks for reply. I get respons in string format "2016-08-15T07:30:43.463Z". Cocos2DX sdk have any function to convert from string representation to seconds since epoch?

Hi Kirill,

As of now, you can get the time in string format from the SDK. But you can convert the same using methods suggested here: http://stackoverflow.com/questions/4137748/c-converting-a-time-string-to-seconds-from-the-epoch .

Please let me know if you have any other queries, I will be happy to help you.

I saw that link. It would be great if response will be as string and long representation since epoch. Here is my implementation.

#if UINT_MAX >= 0xFFFFFFFF
    typedef long cs_time_type;
#else
    typedef unsigned long cs_time_type;
#endif

cs_time_type CloudService::getSecondsSiceEpoch ( const struct tm * ptm )
{
    int m = 0;
    int y = ptm->tm_year;

    if( ( m = ptm->tm_mon ) < 2 )
    {
        m += 12;
        --y;
    }

    return ( ( ( ( cs_time_type )( y - 69 ) * 365u + y / 4 - y / 100 * 3 / 4 + ( m + 2 ) * 153 / 5 - 446 + ptm->tm_mday ) * 24u + ptm->tm_hour ) * 60u + ptm->tm_min ) * 60u + ptm->tm_sec;
}


cs_time_type CloudService::convertTime( const std::string& _time )
{
    cs_time_type result = 0;

    std::tm rawTime;
    std::istringstream timeStream( _time );
    std::memset( &rawTime, 0, sizeof( std::tm ) );

    if( timeStream >> std::get_time( &rawTime, "%Y-%m-%dT%H:%M:%S" ) )
    {
        result = getSecondsSiceEpoch( &rawTime );
    }
    else
    {
        log( "Can't parse time from server!" );
    }

    return result;
}
