Date and Time

This is the group of functions for working with data of datetime type (an integer that represents the number of seconds elapsed from 0 hours of January 1, 1970).

What's new in MQL5

Added the MqlDateTime structure containing eight int type fields:

struct MqlDateTime
  {
   int year;           // year
   int mon;            // month
   int day;            // day
   int hour;           // hour
   int min;            // minutes
   int sec;            // seconds
   int day_of_week;    // day of week (0 - Sunday, 1 - Monday, ..., 6 - Saturday)
   int day_of_year;    // number of a day in a year (January 1 has number 0)
  };

Thus, the new TimeToStruct() and StructToTime() functions allow you to receive and pass data on days, hours, minutes and seconds within a single call.
