Description
This operation performs two types of conversion:
...
How does it work in the search window?
Select Create column in the search window toolbar, then select the Timestamp operation. It only requires one argument, either an integer or a string column.
Argument | Data type | More information |
|---|---|---|
Epoch / Date definition mandatory | integer or string | In the conversion of an epoch date integer into a timestamp, the number introduced will be treated as milliseconds so you need to make sure it actually refers to milliseconds. If you are given a date expressed in seconds, you need to transform it into milliseconds, otherwise the result will not correspond to the real date. You can add three zeros to the end of it using the following LINQ:
Once the epoch date is expressed in milliseconds, you can apply the |
To convert a date field from string to timestamp, the date must follow the format: Year-Month-Day Hour:Minute:Second.Millisecond (i.e. 2019-09-09 09:52:49.986). If your date string doesn't follow the required format, you should instead use the parse date operation to convert it to a timestamp. |
The data type of the values in the new column is timestamp.

Example
The examples in this article use values in a data table generated from the following CSV file.
...
Use the operator select... as... and add the operation syntax to create the new column. These are the valid formats of the operation:
timestamp(integer)timestamp(string)
Example
You can copy the following LINQ script and try the above example on the my.upload.sample.data table. Keep in mind that you must download and upload the file provided before to your Devo domain.
