Set External timestamp.
Files
clk.h / Application’s source file
Called from
Clk_SetTS()
Prototype
Arguments
ts_sec
External timestamp value to set (in seconds, UTC+00).
Returned Values
DEF_OK, if External timestamp succesfully set;
DEF_FAIL, otherwise.
Required Configuration
Required callback function that must be implemented in your application if CLK_CFG_EXT_EN is DEF_ENABLED in clk_cfg.h (see Module Configuration) in order for the clock/calendar to be maintained by an external clock/timestamp mechanism.
Notes / Warnings
External timestamp values are converted from Clock timestamp’s CLK_TS_SEC data type. If the External timestamp has more bits than the CLK_TS_SEC data type, Clk_ExtTS_Set() must pad the External timestamp’s higher order bits with 0 bits. If the External timestamp has less bits than the CLK_TS_SEC data type, Clk_ExtTS_Set() must truncate the Clock timestamp’s higher order bits greater than the External timestamp.
...
This example underflows to a negative External timestamp since the equivalent date to convert is incorrectly less than the External epoch start year.
