seconds to day, month, week, day of the week etc..

[Gyiove]

Hello everyone!

I have server time
int time
It should show what time it is right now on that server.
I should also someone extract all those informations like
day of the week, year etc.. from that variable.

here's how i calculate: day of the week, hour and minutes
[php]
// 0- Sunday, 1 - monday ... 6 -Saturday
inline int GetDay(int time)
{
int d = (time % 604800) / 86400;
d += 4;
if (d > 6) d = d - 7;
return d;
}

inline int GetHour(int time)
{
return (time % 86400) / 3600;
}

inline int GetMinute(int time)
{
return (time % 3600) / 60;
}
[php]

Now the question is, how to get:
month of the year (1-12)
year (2015 for example)
day of the month ( 1-31 )


Thanks!
