ext:format-universal-time destination universal-time &key timezone style date-first print-seconds print-meridian print-timezone print-weekday[Function]

Format a string containing the time and date given by universal-time in a common manner. The destination is any destination which can be accepted by the format function. The timezone keyword is an integer specifying hours west of Greenwich. The style keyword can be :short (numeric date), :long (months and weekdays expressed as words), :abbreviated (like :long but words are abbreviated), :rfc1123 (conforming to RFC 1123), or :government (of the form "XX Mon XX XX:XX:XX"), or :iso8601 (conforming to ISO 8601). The keyword date-first, if nil, will print the time first instead of the date (the default). The print- keywords, if nil, inhibit the printing of the obvious part of the time/date.
