Arguments: stream ut show-date show-time &optional (locale *locale*)fmt
Arguments:
This function outputs to the stream a locale appropriate
representation of the time specified by ut. The
output format can be specified as a string following the XPG4
strftime() format (see below). If
fmt is non-nil, then the date and time booleans
are ignored. Otherwise, if fmt is nil, then the
date and time booleans determine the format based on the following
table:
| show-date | show-time | fmt control string |
| false | false | (locale-t-fmt-ampm locale) |
| false | true | (locale-t-fmt locale) |
| true | false | (locale-d-fmt locale) |
| true | true | (locale-d-t-fmt locale) |
The function locale-format-time can be invoked using the format ~/ directive. The locale argument can be supplied using format's ~v prefix argument. The fmt argument can be supplied as the second prefix argument. The show-date argument is specified using the colon modifier. The show-time argument is specified using the at-sign modifier.
The LC_TIME category defines display formats using conversion specifications which are also defined in the category. The conversion specifications consist of a '%' followed by one or two letters. The formats are intended for the XPG4 strftime() function.
The print-date-time function outputs the date/time as specified by the format string in the same way as strftime(). In addition to the field descriptor definitions, the print-date-time function will interpret the following C escape sequences as follows:
\\ insert #\\ \a insert #\bell \b insert #\backspace \f insert #\page \n insert #\linefeed \r insert #\return \t insert #\tab \v insert #\vt
These are the field descriptor definitions:

If the week containing 1 January has four or more days in the new year, then it is considered week 1; other- wise, it is week 53 of the previous year, and the next week is week 1. %w weekday as a decimal number [0,6], with 0 represent- ing Sunday %W week number of year as a decimal number [00,53], with Monday as the first day of week 1 %x locale's appropriate date representation %X locale's appropriate time representation %y year within century [00,99] %Y year, including the century (for example 1993) %Z time zone name or abbreviation, or no bytes if no time zone information exists
Some conversion specifications can be modified by the E and O modifiers to indicate that an alternate format or specification should be used rather than the one normally used by the unmodified conversion specification. If the alternate format or specification does not exist in the current locale, the behavior will be as if the unmodified specification were used.
