Casting times for Spell-Like Abilities

[Reshy]

Hello, me and a friend of mine are discussing whether or not a Spell-Like ability (by default) has a casting time of 1 standard action unless otherwise noted in the monster's entry. 

Here's the relevant bits I could find concerning spell-like abilities:

Actions in Combat
Spell-Like Abilities

Using a spell-like ability works like casting a spell in that it requires concentration and provokes attacks of opportunity. Spell-like abilities can be disrupted. If your concentration is broken, the attempt to use the ability fails, but the attempt counts as if you had used the ability. The casting time of a spell-like ability is 1 standard action, unless the ability description notes otherwise.

Special Abilities
A spell-like ability usually has a limit on how often it can be used. A spell-like ability that can be used at will has no use limit.  Using a spell-like ability is a standard action unless noted otherwise, and doing so while threatened provokes attacks of opportunity.

Rules Compendium
Using a spell-like ability usually takes 1 standard action and provokes attacks of opportunity unless otherwise noted. If the spell-like ability duplicates a spell that has a casting time of less than 1 standard action, the spell-like ability has that casting time.

As far as I can tell it's a standard action and that's always what I worked off of.  However my friend is insisting that it runs off the base spell's casting ability as that is part of the "Unless Otherwise Noted" section of the entry, whereas as I understand it it refers to the spell-like ability's section specifically for changes to the casting time.

As the Rules Compendium mentions, if the spell the SLA is based off of has a casting time lass than a standard action then the SLA itself has that action too.  For example, if you had Close Wounds as an SLA then it'd be an immediate action.

What's interesting about that specific point is is shortens other spells with a long casting time to just a standard action.  Identify?  Standard action.

So the RC rule messes things up a bit.  Before that ruling it was always just a standard action unless the SLA entry itself said it was different.  It wasn't a function of the spell the SLA was based off of, it was a function of whatever the designers wanted the cast time to be if they made a note that said it was something besides a standard action.
