Find my approach as reference below and stored in attached workbook version 9.3 located in the original thread.
1. date: mid([Created At],1,10)
2. time: mid([Created At],12,9)
3. date time: [Date]+" "+[Time]
4. dateparse: dateparse("yyyy-mm-dd hh:mm:ss",[Date Time])
If a date and a time are displayed on the same line, then always write the date in front of the time. If a date and a time value are stored together in a single data field, then ISO 8601 suggests that they should be separated by a latin capital letter T, as in 19951231T235959.
