{"date": "1970-01-01"} Developer T-Shirt

{"date": "1970-01-01"} is the Unix epoch wearing a JSON date string. It's where time starts counting, and the value that surfaces when a timestamp defaults, a conversion slips, or a field never got set.

As far as the system's concerned, nothing happened before 1970.

Shipping and returns

Shipping costs vary by region, so it's worth giving the delivery total at checkout a quick look before confirming your order. Some variants may show limited availability in certain locations—if fulfilment isn't available in your region, our suppliers will try to ship globally from the nearest facility that can produce that specific item. When this happens, delivery costs may be higher than expected due to the increased distance.

We're constantly reviewing suppliers and expanding fulfilment options, and new routes may open over time.

The Unix Epoch: Why January 1, 1970 is Important in Programming
