Combining Rules

Flexible Time lets you combine different rules to control when parking starts, ends, and what limits apply.

However, not all rules can be used together.

This depends on what the user is selecting vs what is fixed.

The Key Rule

You can only apply rules to fields the user selects.

Each permit includes:

Start Date
Start Time
Expiry Date
Expiry Time

Each of these can either be:

Set by the system (fixed)
Selected by the user

What Rules Can Be Combined

Below is how rules combine based on what the user is selecting.

If Start Date is User Selected

You can use:

Start Date Window

You can also combine with:

Start Time Window (if time is also user-selected)
Any expiry rules
Time Increments
Min / Max Duration

If Start Time is User Selected

You can use:

Start Time Window

You can also combine with:

Time Increments
Min / Max Duration

If Expiry Date is User Selected

You can use:

Expiry Date Window

You can also combine with:

Expiry Time Window (if time is also user-selected)
Min / Max Duration

If Expiry Time is User Selected

You can use:

Expiry Time Window

You can also combine with:

Time Increments
Min / Max Duration

If Both Start and Expiry Are User Selected

You can use all rules together:

Start Date Window
Start Time Window
Expiry Date Window
Expiry Time Window
Time Increments
Min / Max Duration

This is the most flexible setup.

When Rules Cannot Be Combined

If Start Date is Fixed

You cannot use:

Start Date Window

If Start Time is Fixed

You cannot use:

Start Time Window

If Expiry Date is Fixed

You cannot use:

Expiry Date Window

If Both Start and Expiry Are Fully Fixed

You cannot use:

Time Increments
Min / Max Duration

Special Case: Day of Week

Limits which days are allowed
The user still selects a date

Because of this:

You can combine it with:

Start Date Window
Start Time Window

“With Constraints” (Partial Combinations)

Some rules can be combined, but with limits.

This happens when:

Part of the timing is fixed
Part is user-selected

Example

Expiry Date = system set
Expiry Time = user selected

You can use:

Expiry Time Window
Time Increments
Min / Max Duration

But they must fit within the fixed expiry date.
