ECR: DocumentValidationError / Time Stamp - the check is not fiscalized
Software ECR validation error where a receipt or Z-report is not registered due to an incorrect Time Stamp. Critical error: sales and shift closing are blocked.
When does the Time Stamp error occur
-
When conducting a sale or return through the software ECR.
-
When trying to close a shift (generate a Z-report).
-
During the transition from offline to online mode.
How to understand that the problem is exactly in the time stamp
-
The receipt in the Software ECR Analytics section is highlighted in red.
-
The error text contains the words: DocumentValidationError, Time Stamp, InvalidQueryParameter.
-
Full error text: «Error code: 9 DocumentValidationError. The message cannot contain the content time stamp...».
-
It is impossible to close the shift or resend the receipt.
Why the software ECR rejects the receipt due to Time Stamp
-
Time desynchronization (main cause). The time on the computer or server differs from the exact tax server time (even by 1–2 minutes). The qualified electronic signature (QES) strictly fixes the moment of signing.
-
Tax server unavailability. The program cannot receive a time stamp from the electronic service provider.
-
Windows regional settings: An incorrect date format is set (for example, American MM/dd/yyyy), which blocks validation.
How to fix the Time Stamp error
Step 1. Synchronize the operating system time with the Internet (Priority #1)
This solves 90% of cases. You need to synchronize your operating system time with Internet time servers. Also, make sure that the time zone is set correctly (UTC+02:00 or UTC+03:00 for Ukraine).
Important. The synchronization method depends on your workplace. If you work on a local (separate) computer, this can usually be done through the standard Windows clock settings. If the program is used on a remote (terminal) server, changing the time is most often blocked by security policies. In this case, you need to contact your system administrator or the organization providing the server lease to synchronize the time.
Step 2. Restart Torgsoft
A time change is not always applied instantly to running processes.
-
Completely close the program.
-
Launch it again.
-
Try to resend the receipt or generate the report again.
Step 3. Check regional settings
If the time is correct, but the error persists:
-
Open Control Panel → Region.
-
Make sure the Short date format looks like dd.MM.yyyy.
-
Save the settings.
How to verify that the error is resolved
-
Reprocess the problematic document (sales receipt, return, or Z-report) through the software ECR in the program.
-
Open the menu Settings → Software ECR → Software ECR Analytics tab.
-
Find the newly processed document in the list.
-
Check its status: it should be displayed as created in online mode, and the sending column should have a status indicating that the document was successfully sent to the tax office (registered on the fiscal server).
How to prevent the error from recurring
-
Enable automatic time synchronization in Windows.
-
Replace the BIOS battery on the motherboard if the time constantly resets after a power outage.
What is important to remember
If the software ECR returns DocumentValidationError or Time Stamp — immediately synchronize the time on your computer and restart the program.
