Description
Applying an algorithm to a layer which contains a datetime field will result in an ouput that transforms the datetime field into a date-only field, causing time data loss. While a shapefile only supports date field, the memory layer does (as soon as https://github.com/qgis/QGIS/pull/2713 is merged) support datetime field, it'd be nice for processing to preserve datetime when the output if a memory layer.

Updated by Alexander Bruy over 8 years ago
Processing copies fields definition from source layers, so If layer reports field as DateTime and output format/provider supports this data type without conversion it should just work

Alex, it does not over here :) Here's an easy set of steps to reproduce the loss of datetime field:
- Create a new project
- Add the attached test.gpx vector file (choose the track_points layer)
- Open the layer properties window, and take note of the "time" field, identified as a DateTime field type
- Open processing, and select the "Fixed distance buffer" algorithm
- Save the resulting buffer to a memory layer
- Open the layer properties window for the newly created buffer memory layer, and take note of the "time" field, converted to a String field type
