The timestamp must necessarily correspond to the current date and time, in the GMT + 0 (or UTC) time zone in 24h format. Note: If you are using REST payment web services, the equivalent of the vads_trans_date parameter is transactions[0].transactionDetails.cardDetails.legacyTransDate. Input and output field, returned in the response (IPN and Return URL).
Format	n14
Error code	04 Frequent errors: The date has not been submitted in the YYYYMMDDHHMMSS format (year, month, day, hour, minute, second). The date is not based on the UTC time zone (Coordinated Universal Time). Make sure you use date functions in your programming language that will generate a UTC hour (e.g.: gmdate in PHP). The time must be calculated using the 24h format, not 12h. The buyer has waited for too long before clicking on Pay. The buyer was using browser history.
