Managing Color With ColorSync


Date and Time

The ColorSync Manager defines the CMDateTime type for specifying a date and time.


CMDateTime

The ColorSync Manager defines the CMDateTime data structure to specify a date and time in year, month, day of the month, hours, minutes, and seconds. Other ColorSync structures use the CMDateTime structure to specify information such as the creation date or calibration date for a color space profile.

The CMDateTime structure is similar to the Macintosh Toolbox structure DateTimeRec , and like it, is intended to hold date and time values only for a Gregorian calendar.

Note

The CMDateTime structure is platform independent. However, when used with Macintosh Toolbox routines such as SecondsToDate and DateToSeconds , which use seconds to designate years, the range of years that can be represented is limited.

struct CMDateTime {
    unsigned short  year;
    unsigned short  month;
    unsigned short  dayOfTheMonth;
    unsigned short  hours;
    unsigned short  minutes;
    unsigned short  seconds;
};
year
The year. Note that to indicate the year 1984, this field would store the integer 1984, not just 84.
month
The month of the year, where 1 represents January, and 12 represents December.
dayOfTheMonth
The day of the month, ranging from 1 to 31.
hours
The hour of the day, ranging from 0 to 23, where 0 represents midnight and 23 represents 11:00 P.M.
minutes
The minutes of the hour, ranging from 0 to 59.
seconds
The seconds of the minute, ranging from 0 to 59.
