What happens when StringToTime fails to convert a string to datetime?

The MQL5 documentation does not say how an error is indicated.

[Stanislav Korotky]

You can find some info in the book:

If the supported syntax in the string is broken, the result is the current date.

...

In addition to StringToTime, you can use the cast operator (datetime) to convert strings to dates and times. However, the advantage of the function is that when an incorrect source string is detected, the function sets an internal variable with an error code _LastError (which is also available via the function GetLastError). Depending on which part of the string contains uninterpreted data, the error code could be ERR_WRONG_STRING_DATE (5031), ERR_WRONG_STRING_TIME (5032) or another option from the list related to getting the date and time from the string.

This behavior information should be added to the online MQL5 documentation.

Thanks.
