`merchantTransactionDate` date-time required	The date and time when the transaction happened, in ISO 8601 format.

For example, GBP 1.1 = GBP 1.10, EUR 1 = EUR 1.00, or BHD 1.3 = 1.300. The transaction will be rejected if numbers after the decimal are greater than the expected `currencyCode` exponent (e.g., GBP 1.234), or if a decimal is supplied when the `currencyCode` of the exponent does not require it (e.g., JPY 1.0).
