Format-Universal-Time formats 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), or :GOVERNMENT (of the form “XX Month XXXX XX:XX:XX”)
The &KEY argument :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.
