Description
Return signed elapsed days between two medication-record dates.
Pharmacy administration distinguishes medicine and document identifiers, service records, stock balances and payment conventions from decisions about care. Literal labels and supplied status flags help reconcile records, while medicine identity, appropriate treatment and actual availability require independent verification.
Return signed elapsed days between two medication-record dates.
When to use this tool

}Limitations and assumptions
- The modern parser accepts four-digit years 0000-9999; no local-zone day length, clinical interval or expiry rule is selected.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Inspect verified medicine and service records and the applicable professional procedures; use appropriate clinical systems and qualified professional judgment for care or supply decisions.
