Facet used for format-based output of time types This class provides for the use of format strings to output times. In addition to the flags for formatting date elements, the following are the allowed format flags:
x X => default format - enables addition of more flags to default (ie. "%x %X %z")
f => fractional seconds ".123456"
F => fractional seconds or none: like frac sec but empty if frac sec == 0
s => seconds w/ fractional sec "02.123" (this is the same as "%S%f) - %S => seconds "02" - %z => abbreviated time zone "EDT" - %Z => full time zone name "Eastern Daylight Time"
