How to disallow content "time" in noindex?

Question

Yandex

The problem is this: the
Yandex robot recognizes completely different pages of the site as duplicates.
Technical support explains this by the fact that a callback is set on the pages, there is a field for a convenient call time. This is how the source code looks like:
10:0010:3011:0011:3012:0012:3013:00
Yandex advises to close the time content using noindex.
How to do it? Where to prescribe?
Joomla engine.
