#define TOD_BASE_YEAR 1988 |
Earliest year to which an time of day can be initialized.
The following constant define the earliest year to which an time of day can be initialized. This is considered the epoch.
#define TOD_SECONDS_1970_THROUGH_1988 |
Seconds from January 1, 1970 to January 1, 1988. Used to account for differences between POSIX API and RTEMS core. The timespec format time is kept in POSIX compliant form.
