Convert Unix timestamp to a date/time structure.

Files

clk.h/clk.c

Prototype

CPU_BOOLEAN  Clk_TS_UnixToDateTime (CLK_TS_SEC      ts_unix_sec,
                                    CLK_TZ_SEC      tz_sec,
                                    CLK_DATE_TIME  *p_date_time);

Arguments

ts_unix_sec

Timestamp to convert (in seconds, UTC+00).

tz_sec

Time zone offset (in seconds, ± from UTC).

p_date_time

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

Returned Values

DEF_OK, if date/time structure successfully returned.

DEF_FAIL, otherwise.

Required Configuration

Available only if CLK_CFG_UNIX_EN is DEF_ENABLED in clk_cfg.h (see Module Configuration).

Notes / Warnings

Timestamp (ts_unix_sec) must be set for UTC+00 and should not include the time zone offset (tz_sec) since Clk_TS_UnixToDateTime() includes the time zone offset in its date/time calculation. Thus the time zone offset should not be applied before or after calling Clk_TS_UnixToDateTime(). Time zone field of the date/time structure (p_date_time->TZ_sec) is set to the value of the time zone argument (tz_sec).

Example Usage

Listing - Clk_TS_UnixToDateTime() Example Usage

CLK_DATE_TIME  date_time;
CLK_TS_SEC     ts_unix_sec;
CLK_TZ_SEC     tz_sec;
CPU_BOOLEAN    valid;
 
ts_unix_sec =   1000000;
tz_sec      = -5 * 3600;
valid       = Clk_TS_UnixToDateTime(ts_unix_sec, tz_sec, &date_time);
if (valid == DEF_OK) {
    printf("Timestamp successfully converted\n\r");
} else {
    printf("Timestamp conversion error\n\r");
}
