/* Just like strftime, but with two more arguments:

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
|
|
plus some requested changes to POSIX. */
