What the default duration for Utility Powers?

[volanin]

Examples:


Ranger Utility 16: Longstrider
Daily
Minor Action
Effect: Speed increases by 2.

Ranger Utility 22: Master of the Hunt
Daily
Minor Action
Effect: Bonus to damage = WIS modifier.


These are high level DAILY powers.
But do they grant you the bonuses just for ONE SINGLE ACTION in the same round, or they work for a longer duration?

Those powers have the 'Stance' keyword which, according to PHB pg55, means they last until the end of the encounter, for 5 minutes, or until you use another stance power.
