It seems like better having the server deliver the timestamp format string to be used in conditional expressions.
@ mh0203 will work on it.

서버에서 조건문에 사용할 timestamp format string을 함께 내리는 것이 좋겠습니다.
@mh0203 님께서 작업하실 예정입니다.

This request is resolved as follows

1. Histogram gives labels and real timestamp value both.
2. Add a new function to determine if a given time value is within range.
