+.Nd parse date and time string
+.Sh SYNOPSIS
+.Fd #include <time.h>
+.Ft const char *
+.Fn strptime "const char *buf" "const char *format" "struct tm *timeptr"
+.Sh DESCRIPTION
+The
+.Fn strptime
+function parses the string in the buffer
+.Fa buf
+according to the string pointed to by
+.Fa format ,
+and fills in the elements of the structure pointed to by
+.Fa timeptr .
+Thus, it can be considered the reverse operation of
+.Xr strftime 3 .
+.Pp
+The
+.Fa format
+string consists of zero or more conversion specifications and
+ordinary characters.
+All ordinary characters are matched exactly with the buffer, where
+white space in the format string will match any amount of white space
+in the buffer.
+All conversion specifications are identical to those described in
+.Xr strftime 3 .
+.Sh RETURN VALUES
+Upon successful completion,
+.Fn strptime
+returns the pointer to the first character in
+.Fa buf
+that has not been required to satisfy the specified conversions in
+.Fa format .
+It returns
+.Dv NULL
+if one of the conversions failed.
+.Sh SEE ALSO
