+%u is the numeric day of week from 1 (Monday) to 7, %w from 0 (Sunday) to 6.
+%a is the locale's abbreviated name of the day of week, %A the full name.
+%U is the week number starting on Sunday, %W starting on Monday,

+%H is the hour on a 24-hour clock, %I is on a 12-hour clock, %k is like %H

+%p is the locale's equivalent of either AM or PM.
+%M is the minute.
+%S is the second.
+%Z is the time zone name, %z is the numeric form.
+%s is the number of seconds since 1970-01-01 00:00:00 +0000.
+
+%c is the locale's date and time format.
+%x is the locale's \"preferred\" date format.
+%D is like \"%m/%d/%y\".
+
+%R is like \"%H:%M\", %T is like \"%H:%M:%S\", %r is like \"%I:%M:%S %p\".
+%X is the locale's \"preferred\" time format.
+
+Finally, %n is a newline, %t is a tab, %% is a literal %.
+
+Certain flags and modifiers are available with some format controls.
+The flags are `_' and `-'. For certain characters X, %_X is like %X,
+but padded with blanks; %-X is like %X, but without padding.
+%NX (where N stands for an integer) is like %X,
+but takes up at least N (a number) positions.
+The modifiers are `E' and `O'. For certain characters X,
+%EX is a locale's alternative version of %X;
+%OX is like %X, but uses the locale's number symbols.
