Can Piwik record Visit length if there was only 1 action?

In the Visitor log there are visit lenghts only for visitors with more than 1 action. In Length of visits diagram I see 80% of visits 0-10s. Does this mean that Piwik just cannot track real length and set it to 0 for visits with one action? Thank you.
