-/* Note: this version of strftime lacks locale support,
- but it is standalone.
-
- Performs `%' substitutions similar to those in printf. Except
- where noted, substituted fields have a fixed size; numeric fields are
- padded if necessary. Padding is with zeros by default; for fields
- that display a single number, padding can be changed or inhibited by
- following the `%' with one of the modifiers described below. Unknown
- field specifiers are copied as normal characters. All other
- characters are copied to the output without change.
-
- Supports a superset of the ANSI C field specifiers.
-
- Literal character fields:
- % %
- n newline
- t tab
-
- Numeric modifiers (a nonstandard extension):
- - do not pad the field
- _ pad the field with spaces
-
- Time fields:
- %H hour (00..23)
- %I hour (01..12)
- %k hour ( 0..23)
- %l hour ( 1..12)
- %M minute (00..59)
- %p locale's AM or PM
- %r time, 12-hour (hh:mm:ss [AP]M)
- %R time, 24-hour (hh:mm)
- %s time in seconds since 00:00:00, Jan 1, 1970 (a nonstandard extension)
- %S second (00..61)
- %T time, 24-hour (hh:mm:ss)
- %X locale's time representation (%H:%M:%S)
- %Z time zone (EDT), or nothing if no time zone is determinable
-
- Date fields:
- %a locale's abbreviated weekday name (Sun..Sat)
- %A locale's full weekday name, variable length (Sunday..Saturday)
- %b locale's abbreviated month name (Jan..Dec)
- %B locale's full month name, variable length (January..December)
- %c locale's date and time (Sat Nov 04 12:02:33 EST 1989)
- %C century (00..99)
- %d day of month (01..31)
- %e day of month ( 1..31)
- %D date (mm/dd/yy)
- %h same as %b
- %j day of year (001..366)
- %m month (01..12)
- %U week number of year with Sunday as first day of week (00..53)
- %w day of week (0..6)
- %W week number of year with Monday as first day of week (00..53)
- %x locale's date representation (mm/dd/yy)
- %y last two digits of year (00..99)
