This was my understanding as well.
By those definitions there is no such thing as a "CCS" amateur amp. "No Time
Limit" is just marketing fluff.

Subject: [Amps] Defining CCS
Ok, I have had it with vague sales statements. The following was used since at
least 1955 and all amp experts know it.
CCS is Continuous Commercial Service. This is true 100% duty cycle, BRICK ON
THE KEY, rating indicating operations for 24/7/365 with no off times.
No sales talk juggling.
ICAS is Intermittent Commercial and Amateur Service. That means typical
on-and-off ham operations without long key-down transmissions (usually 10
minutes is called long). This is NOT 100% duty cycle but indicates use of full
power with limited key-down times and definite key-up times.
An amp can be called 100% ICAS by imaginative advertising writers, but that
number is definitely not CCS.
It is helpful to hold to old established nomenclature for clear communication.
