| POSIX requires that strftime use the local timezone information. | |
| Use the timezone __TZ instead. Use __NS as the number of | |
| nanoseconds in the %N directive. | |
| On error, set errno and return 0. Otherwise, return the number of | |
| bytes generated (not counting the trailing NUL), preserving errno | |
| if the number is 0. This errno behavior is in draft POSIX 202x | |
