I am reading a feature class stored in ArcGIS Enterprise database and I would like to output a json file.
However, I need the datetime fields values to be in epoch time (with milliseconds) not in FME datetime format.
I am using the DateTimeConverter transformer with the %s Output format parameter
For instance I need this translation
2021020511442300 ---> 1612543463000
However the transformer return the following error:
DateTimeConverter: Failed to evaluate expression '@DateTimeFormat(20210127152551,%s)'. Result is set to null
Format flag '%s' is not supported for input type 'datetime'. Please check @DateTimeFormat() documentation in https://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_Workbench/!Transformer_Parameters/Date-Time-Functions.htm in the subsections 'Arguments' and 'Format String Flags', for supported flags and exclusion lists
