Workflow Condition - how do check that a date / time value is in the past?

Hello,

I'm got a workflow that runs a function when records reach their 'Effective Date / Time', but sometimes records are created after the 'Effective Date / Time' so I have another workflow that checks for records which needs to be processed immediately.

It's this second scenario that I'm struggling with. How do I trigger a Zoho Workflow when a record is created with a field (Effective Date / Time) which has a date time in the past? Not just a date in the past.

I've tried the following conditions:

Effective Date / Time AGE IN DAYS <= 0
This runs the workflow for records where the Effective Date / Time is today but in the future (e.g. this afternoon).

Effective Date / Time IS Till Yesterday
This runs the workflow for records where the Effective Date / Time is yesterday, but that means that any that are created today but in the past (e.g. this morning) are missed.

Most of the other options seem to be for specific rather than dynamic dates. What am I missing? I want the condition to check the date / time is in the past.

Thanks!
