_get_dstbias
Retrieves the daylight saving time offset in seconds.
error_t _get_dstbias(
int* seconds
);
Parameters
- seconds
The offset in seconds of daylight saving time.
Return Value
Zero if successful or an errno value if an error occurs.
Remarks
The _get_dstbias function retrieves the number of seconds in daylight saving time as an integer. If daylight saving time is in effect, the default offset is 3600 seconds, which is the number of seconds in one hour (though a few regions do observe a two-hour offset).
If seconds is NULL, the invalid parameter handler is invoked as described in Parameter Validation. If execution is allowed to continue, this function sets errno to EINVAL and returns EINVAL.
We recommend you use this function instead of the macro _dstbias or the deprecated function __dstbias.
