Clk_SetDateTime

Set Clock timestamp from a date/time structure.

Files

clk.h/clk.c

Prototype

CPU_BOOLEAN Clk_SetDateTime (CLK_DATE_TIME *p_date_time);

Arguments

p_date_time

Pointer to variable that contains the date/time structure.

Returned Values

DEF_OK, if Clock timestamp is successfully set.

DEF_FAIL, otherwise.

Required Configuration

None.

Notes / Warnings

Date/time (p_date_time) should be set to local time with correct time zone offset (p_date_time->TZ_sec). Clk_SetDateTime() removes the time zone offset from the date/time to calculate the Clock timestamp as UTC+00.

Internal Clock time zone is set to the local time zone offset (p_date_time->TZ_sec).

Example Usage

Listing - Clk_SetDateTime() Example Usage

CLK_DATE_TIME  date_time;
CPU_BOOLEAN    valid;
 
date_time.Yr      =   2010;     /* 2010/09/18  11:11:11 UTC-05:00  */
date_time.Month   =      9;
date_time.Day     =     18;
date_time.Hr      =     11;
date_time.Min     =     11;
date_time.Sec     =     11;
date_time.DayOfWk =      2;
date_time.DayOfYr =    291;
date_time.TZ_sec  = -18000;
 
valid = Clk_SetDateTime(&date_time);
if (valid == DEF_OK) {
    printf("Date/time successfully set");
} else {
    printf("Clock Set Date/time error\n\r");
