For an alternative with custom date formatting, see strftime. Parameters timeptr Pointer to a tm structure that contains a calendar time broken down into its components (see struct tm). Return Value A C-string containing the date and time information in a human-readable format. The returned value points to an internal array whose validity or value may be altered by any subsequent call to. Example 2: Format code — '%c' to display the current localtime. Format code - '%c' is used to display the current localtime which follows the following format: Day Month Date hours:mins:sec Year. from time import strftime day = strftime(%c) print(Current timestamp:, day) Output: Current timestamp: Tue Apr 28 16:42:22 202 The strptime () function processes the input string from left to right.

STRFTIME(3) Manuel du programmeur Linux STRFTIME(3) NOM strftime - Formater la date et l'heure.SYNOPSIS #include <time.h> size_t strftime (char *s, size_t max, const char *format, const struct tm *tm); DESCRIPTION La fonction strftime() formate les divers champs de la structure tm en fonction de la chaîne de spécification format, puis place le résultat dans la chaîne s de taille max This method is similar to strftime() function defined in ISO C and POSIX. Several directives (%a, %A, %b, %B, %c, %p, %r, %x, %X, %E*, %O* and %Z) are locale dependent in the function. However this method is locale independent since Ruby 1.9. So, the result may differ even if a same format string is used in other systems such as C. It is good.

However, this method is locale independent. So, the result may differ even if the same format string is used in other systems such as C.

Note: Not all conversion specifiers may be supported by your C library, in which case they will not be supported by PHP's strftime(). Additionally, not all platforms support negative timestamps, therefore your date range may be limited to no earlier than the Unix epoch. This means that e.g. %e, %T, %R and %D (there might be more) and dates prior t The wcsftime function supports the same flags, modifiers, and format specifiers as the strftime function. The return value of wcsftime is the number of wide characters stored in s. When more characters would have to be written than can be placed in the buffer s the return value is zero, with the same problems indicated in the strftime documentation
