       %%     a literal %

       %a     locale's abbreviated weekday name (e.g., Sun)

       %A     locale's full weekday name (e.g., Sunday)

       %b     locale's abbreviated month name (e.g., Jan)

       %B     locale's full month name (e.g., January)

       %c     locale's date and time (e.g., Thu Mar  3 23:05:25 2005)

       %C     century; like %Y, except omit last two digits (e.g., 21)

       %d     day of month (e.g, 01)

       %I     hour (01..12)

       %j     day of year (001..366)

       %k     hour ( 0..23)

       %l     hour ( 1..12)

       %m     month (01..12)

       %M     minute (00..59)

       %n     a newline

       %N     nanoseconds (000000000..999999999)

       %p     locale's equivalent of either AM or PM; blank if not known

       %P     like %p, but lower case

       %r     locale's 12-hour clock time (e.g., 11:11:04 PM)

       %R     24-hour hour and minute; same as %H:%M

       %s     seconds since 1970-01-01 00:00:00 UTC

       %S     second (00..60)

       %t     a tab

       %T     time; same as %H:%M:%S

       %u     day of week (1..7); 1 is Monday

       %U     week number of year, with Sunday as first day of week (00..53)

       %V     ISO week number, with Monday as first day of week (01..53)

       %w     day of week (0..6); 0 is Sunday

       %W     week number of year, with Monday as first day of week (00..53)

       %x     locale's date representation (e.g., 12/31/99)

       %X     locale's time representation (e.g., 23:13:48)

       %y     last two digits of year (00..99)

       %Y     year

       %z     +hhmm numeric timezone (e.g., -0400)
              (zero) pad with zeros ^ use upper case if possible #  use  oppo-
              site case if possible

       After  any  flags  comes  an optional field width, as a decimal number;
       then an optional modifier, which is either E to use the locale's alter-
       nate  representations  if available, or O to use the locale's alternate
       numeric symbols if available.

ENVIRONMENT

       TZ     Specifies the timezone, unless overridden by command line param-
              eters.  If neither is specified, the setting from /etc/localtime
              is used.
