When we use the phrase 'with regards' in a sentence does it always have to be followed by 'to' as in 'with regards to'?

To clarify further take a look at the following examples:

You should be more productive with regards your time.

You should be more productive with regards to your time.

Which of the above is more correct?
Only the second is possible, but 'regard', not 'regards'. However, this is also worth reading:

'Although sometimes considered poor substitutes for about or concerning, the phrases as regards, in regard to, and with regard to are standard and occur in all varieties of spoken and written English, especially in business writing: As regards your letter of January 19.In regards to, and with regards to are widely rejected as errors.'
