Time between allow else error...

[WestAU]

Sorry to ask what i thought would be an easy to find answer LOL.

I am trying to do the following...

if current time is between 07:00-09:00 allow the following for that time then continue to return NOk until next day between same time.

everything i read is finding time between 2 times or adding a sleep timer. im after a block between set times based on current time.

  	if (ud->idx[2] == 0x1A && ud->idx[3] == 0x2A)
	{
	logscreen("Allowed Between 07:00-09:00");  
 	return OK; 
	}else return NOk;

I do thank you in advance.

Need to also check tm_min and tm_sec - current time may be 09:32:46

#include <ctime>

static std::time_t today_at( int hh, int mm = 0 )
{
    const auto now = std::time(nullptr) ;
    auto tm = *std::localtime( std::addressof(now) ) ;
    tm.tm_hour = hh ;
    tm.tm_min = mm ;
    tm.tm_sec = 0 ;
    return std::mktime( std::addressof(tm) ) ;
}

static bool is_login_allowed_now()
{
    const auto now = std::time(nullptr) ;
    return now >= today_at(7) && now <= today_at(9) ;
}

Thanks i will give this ago, basically i want to simply allow connection standard but between the 0700-0900 restrict a couple of things then allow again after set time.
