The tf and related functions can take name-value pairs to define such as 'TimeUnit'. From the tf documentation:

• Any of the previous syntaxes can be followed by property name/property value pairs
• 'Property',Value
• Each pair specifies a particular property of the model, for example, the input names or the transfer function variable. For information about the properties of tf objects, see Properties. Note that
• sys = tf(num,den,'Property1',Value1,...,'PropertyN',ValueN)
• is a shortcut for
• sys = tf(num,den)
• set(sys,'Property1',Value1,...,'PropertyN',ValueN)

See the Properties section (a bit more than half way down the page) for details.
