Documentation in section "Service monitoring"

Link: https://www.zabbix.com/documentation/current/manual/it_services

Problem:

Documentation don't explain how SLA is calculated if we define overlapping periods.

Define downtime:

Monday 07:00 - Monday 10:00

Define uptime:

Monday 07:00 - Monday 18:00

Time 07:00 - 10:00 is in SLA calculation or not? What take precedence downtime or uptime?

Expected:

Documentation should explain how SLA is calculated if we define overlapping periods, what take precedence downtime or uptime.
