Past/present toggle - labelling

[planetf1]

Repository explorer has a dialog area for selecting past or present search:

In this dialogue the word 'Past' is on the Right hand side of the toggle. If moved to the right the text updates to present -- ie the function is correct.

However that initial sceen (looking only at the toggle) implies the right side means 'past', when in fact it doesn't. WHen this is combined with the title 'past of present?' I think it makes it somewhat ambigous

how about inverting this to have

'Historical query' as the text, with no words at all
Or if there are words either have something which is clearly on/off, or have labels both side of the toggle
