strftime
| Format: strftime( [ format, ] time ) |
Purpose: Format a time value. The format parameter must denote a string. If the format parameter is not given, it defaults to "%c". The time parameter must denote an object containing the broken down time as returned by localtime() or gmtime(). The structure of a broken down time object is described in localtime().
Return Values: Returns a string that is the result of formatting the time parameter with the format parameter.
The format string consists of zero or more conversion specifications and ordinary characters. A conversion specification consists of a '%' (percent) character followed by a character that determines the specification's behavior. Ordinary characters are copied unchanged into the result string. Each conversion specification is replaced by appropriate characters as described in the following list.
| conversion | replacement |
|---|---|
| %% | percent character |
| %a | abbreviated weekday name |
| %A | full weekday name |
| %b | abbreviated month name |
| %B | full month name |
| %c | default date and time representation |
| %d | day of month, two digits 01-31 |
| %H | hour, two digits 00-23 |
| %I | hour, two digits 01-12 |
| %j | day of the year, three digits 001-366 |
| %m | month number, two digits 01,12 |
| %M | minute, two digits 00-59 |
| %p | a.m. or p.m. designation of the 12-hour clock |
| %S | second, two digits 00-61. |
| %U | week number of the year (the first Sunday as the first day of week 1), two digits 00-53 |
| %w | weekday number, 0-6, Sunday is 0 |
| %W | week number of the year (the first Monday as the first day of week 1), two digits 00-53 |
| %x | default date representation |
| %X | default time representation |
| %y | year within century, two digits 00-2004 |
| %Y | year with century |
| %Z | time zone name or abbreviation, or nothing if time zone is unknown |
