ProcessScheduling

Usually one needs to define when a process needs to run and what period it should cover, thus one way to reason about it is:

• Time Zone - This shall define the Time Zone both for Schedule and Reference Time IANA tz database
• Schedule - When and how often shall the process run - CRON syntax, with defined Time Zone
• Reference Time - Anchor from where to build the Period current (minute, hour, day, week, month, year etc.)
• Period Start - Time duration from Reference Time - ISO 8601 Duration
• Period Duration - The duration of the period from Period Start - ISO 8601 Duration

Sometimes there is also need to define a Gate with it's open and close times.

• Gate Open - Time before Period Start when data will be accepted for processing - ISO 8601 Duration
• Gate Close - Time before Period Start when data is not anymore accepted - ISO 8601 Duration
