Durations in Microseconds

Duration values (e.g. pendingAfter, overdueAfter) are represented as integers in microseconds.

This aligns with PostgreSQL's interval type, which stores durations with microsecond precision.

Duration	Microseconds
1 hour	3,600,000,000
1 day	86,400,000,000
1 week	604,800,000,000
