Calculation of Active Events passes hour filter

[aj0031724]

Dear team,

Need your help to figure out the possible solution.

There are tow time columns (Uptime and Downtime of any event/alarm) and we need to achieve like :

An event will pass a time filter if for any time duration, the event  was active within the time defined by the time filter.

For example->

Table structure like:

DATE	ALARMUPTIME	ALARMDOWNIME	ALARMID
3/3/2017	3/3/2017 17:15	1
3/4/2017	3/3/2017 17:15	1
3/5/2017	3/3/2017 17:15	3/5/2017 16:47	1

Here Alarmid=1 has uptime of  3/3/2017 17:15 AND finished on downtime of =3/5/2017 16:47.

So it remain active till 3/5/2017 16:47.

So if below are filter selections then:

Exmaple 1 ) Date filter: 3/3/2017, 5/3/2017

Hour Filter: 16:00

Alarm Up time: 3/3/2017 17:15:06

Alarm Down time: 5/3/2017 15:47:13

Calculation->Fails the time filter (Events not vsisble)

Exmaple 2 ) Date filter: 3/3/2017, 3/4/2017, 5/3/2017

Hour Filter: 16:00

Alarm Up time: 3/3/2017 17:15:06

Alarm Down time: 5/3/2017 15:47:13

Calculation ->Pass the time filter.(Events will be visible)

Can you please advise how can I achive something like above to pass/fail  the hour filter?
