Bi Publisher, a robust tools suite used for customer communications management, can sometimes cause confusion with its date handling in Excel, particularly when encountering the "1 0 1900" issue. This article delves into understanding and resolving this date anomaly.
The problem arises from Excel's usage of the 1900 date system, where the date January 1, 1900, is represented as "1". Thus, "1 0 1900" corresponds to the time 01:00 AM on January 1, 1900.
The Underlying Cause
The root of this issue lies in the difference between Excel's and Bi Publisher's date interpretation. While Excel uses the 1900 date system, Bi Publisher employs the more standard 1970 date system, making "1 0 1900" nonsensical for it.
To mitigate this, implementing temporary date formats can help bypass this conflict.
Temporary Date Format Change in Bi Publisher
Bi Publisher allows for altering the output format to accommodate the Excel date format. The "xx/yy" format can be used to represent the day of the month.
Consider this example. If the current date is set to "MM/DD/YYYY", change it temporarily to "01/01/1900" to represent "1 0 1900" correctly.
Using Daterolleups in Bi Publisher
Daterolleups is an advanced functionality in Bi Publisher that can handle time conversions. This method requires additional setup and may necessitate expert consultation.
It involves creating a dynamic register and writing the appropriate SQL statements to convert the time up to a familiar format.
Excel's Workaround: Date Formatting
transformé in Excel to handle this date interpretation discrepancy. One approach is to apply a custom date format.
Select the cells with the date, go to "Number" in the "Home" tab, click "Custom", and input "/1900". This adjusts the date display to "1/0/1900".
Excel's Date/Time Function
Excel's built-in DATE and TIME functions can help convert "1 0 1900" to a recognizable time. Enter the formula "=TIME(1, 0, 0)" to represent the 1:00 AM component.
The formula "=DATE(1900, 1, 1)" can represent the date part. Combine both with "="&DATE(1900, 1, 1)&TIME(1, 0, 0) to get a complete datetime value in the Excel 1900 date system.
Always remember to keep your dates in a consistent format for seamless integrations between Bi Publisher and Excel. Regularly review date formats to avoid compromising data integrity.
