CPU_BOOLEAN  Clk_DateTimeMake (CLK_DATE_TIME  *p_date_time,
                               CLK_YR          yr,
                               CLK_MONTH       month,
                               CLK_DAY         day,
                               CLK_HR          hr,
                               CLK_MIN         min,
                               CLK_SEC         sec,
                               CLK_TZ_SEC      tz_sec);

Arguments

p_date_time

Pointer to variable that will receive the date/time structure.

yr

Year value [CLK_EPOCH_YR_START to CLK_EPOCH_YR_END).

month

Month value [CLK_MONTH_JAN to CLK_MONTH_DEC].

day

Day value [1 to 31].

hr

Hours value [0 to 23].

min

Minutes value [0 to 59].

sec

Seconds value [0 to 60].

tz_sec

Time zone offset (in seconds, ± from UTC) [-43200 to 43200].

Returned Values

DEF_OK

, if date/time structure successfully returned.

DEF_FAIL

, otherwise.

Required Configuration

None.

Notes / Warnings

Date/time structure (p_date_time) must be representable in Clock timestamp. Thus date to convert must be greater than or equal to CLK_EPOCH_YR_START and less than CLK_EPOCH_YR_END.

Example Usage

Listing - Clk_DateTimeMake() Example Usage

CLK_DATE_TIME  date_time;
CPU_BOOLEAN    valid;
 
                                  /* 2010/09/18   11:11:11 UTC-05:00  */
valid = Clk_DateTimeMake(&date_time, 2010, 9, 18, 11, 11, 11, -18000);
if (valid == DEF_OK) {
    printf("Date/time successfully created");
} else {
    printf("Clock Date/time error\n\r");
}
