Thank you for review @gabrielreid, i've solved that.
I realized
[TIMEZONE_OFFSET](https://github.com/apache/phoenix/blob/master/phoenix-core/src/main/java/org/apache/phoenix/expression/function/TimezoneOffsetFunction.java#L48)
have similar issue. I think we should rather extract timezone cache mechanism
and make it as part of org.apache.phoenix.cache. Or are there some other
use-cases of (instance) cache so we could implement it more generally?
