Ring of Peace blanket silence bug?

[Tangra]

I'm sorry if this has been reported before, as surely someone has already noticed; but here it is again since it's a pretty nasty bug that doesn't seem to have been fixed even thought it has been around for weeks if not more. The initial blanket silence of RoP is supposed to be 4 sec as listed in the tooltip, after some testing, it is pretty clear that the silence only lasts for 3 seconds, which is of course is a complete and utter deal breaker in PvP. I tested on a variety of mobs and players, so it is not due to silence reducing effects.

2-1-0.

Looks like 3 seconds to me too.

Tooltip starts at 4 seconds, but right as it drops below 4 seconds, it displays 3 seconds. So even if duration is 3.9999 seconds, tooltip will display 3 seconds, not 4.

This is also true for all other buffs

The silence does indeed only last 3secs, while the disarm lasts 4:
