By default, date pads numeric fields with zeroes. GNU date recognizes the following modi-
fiers between `%' and a numeric directive.
`-' (hyphen) do not pad the field `_' (underscore) pad the field with spaces
TZ Specifies the timezone, unless overridden by command line parameters. If neither
is specified, the setting from /etc/localtime is used.
