Clk_TS_ToTS_NTP

Convert Clock timestamp to NTP timestamp.

Files

clk.h/clk.c

Prototype

CPU_BOOLEAN  Clk_TS_ToTS_NTP (CLK_TS_SEC   ts_sec,
                              CLK_TS_SEC  *p_ts_ntp_sec);

Arguments

ts_sec

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

p_ts_ntp_sec

Pointer to variable that will receive the NTP timestamp:

In seconds UTC+00, if no errors;
CLK_TS_SEC_NONE, otherwise.

Returned Values

DEF_OK, if timestamp successfully converted.

DEF_FAIL, otherwise.

Required Configuration

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

Notes / Warnings

Returned timestamp does not include any time zone offset. Thus any local time zone offset should be applied before or after calling Clk_TS_ToTS_NTP().

Only years supported by Clock and NTP can be converted, thus the timestamp date must be greater than or equal to CLK_EPOCH_YR_START and less than CLK_NTP_EPOCH_YR_END.

Example Usage

Listing - Clk_TS_ToTS_NTP() Example Usage

CLK_TS_SEC   ts_sec;
CLK_TS_SEC   ts_ntp_sec;
CPU_BOOLEAN  valid;
 
ts_sec = 0;
valid  = Clk_TS_ToTS_NTP(ts_sec, &ts_ntp_sec);
if (valid == DEF_OK) {
    printf("Timestamp = %u", ts_ntp_sec);
} else {
    printf("Convert timestamp error\n\r");
}
