Should the production date of mixed halva be based on the packaging date or on the production date of its oldest component?

Truthfulness is required in dealings and is affirmed when it relates to people's health. Lying is forbidden, especially if it harms them, as the Messenger of Allah, peace and blessings be upon him, said: "Indeed, truthfulness leads to righteousness, and righteousness leads to Paradise. A man continues to tell the truth until he becomes a truthful person (Siddiq). And indeed, lying leads to wickedness, and wickedness leads to the Hellfire. A man continues to lie until he is recorded with Allah as a liar." The obligation is to be cautious in truthfulness and for the safety of people. It seems that writing the packing date close to the production date is sufficient to achieve truthfulness and people's safety, provided that no harm results from its delay.
