Wand question

[Yqatuba]

I noticed for wands it usually says "activation: cast a spell". Does this mean it takes the same amount of time to activate as the spell it casts? If not, what does it mean?

Casting Spells from a Wand CRB page 597 wrote:

Casting a spell from a wand requires ... activating the item with a Cast a Spell activity using the normal number of actions for the spell. ... use your spell attack roll and spell DC.

Since you're using the Cast a Spell activity, you can also use metamagic with a wand.
