| 46 | * FreeBSD 5.1
|
|---|
| 47 | *
|
|---|
| 48 | * @changed EMX isms.
|
|---|
| 49 | * @changed Removed timezone() function as it clashes with the timezone
|
|---|
| 50 | * variable defined in EMX and OGBSI6.
|
|---|
| 51 | * @changed Changed CLK_TCK and CLOCKS_PER_SEC to 100.
|
|---|
| 52 | * @changed Commented out tm_gmtoff and tm_zone in struct tm as LIBC doesn't
|
|---|
| 53 | * implement these yet.
|
|---|
| 54 | *
|
|---|
| 55 | * @todo Implement tm_gmtoff and tm_zone members in struct tm.
|
|---|
| 56 | * @todo Implement clock_getres(), clock_gettime(), clock_settime(), nanosleep().
|
|---|
| 57 | * asctime_r(), ctime_r(), gmtime_r() and localtime_r() which are defined in
|
|---|
| 58 | * various POSIX standard revisions.
|
|---|
| 59 | * @todo Implement tzsetwall(), timelocal(), timegm() which are BSD specific.
