Timestamp example but with array

[OmarK124]

Sorry if this might seem lazy/obvious for some of you, but I've been struggling to get this to work.
Like AppendMapValueTimestamp.ino

Except I'd like to append maps (which contain a timestamp field) to an array, and not have a map of maps

i.e.

[ { timestamp: May 9 } ]
Instead of
{ key1: { timestamp: May 9 } }

Thank you.

Timestamp is not a value that provided by user but operation/transaction timestamp.

You have to know field path to set the timestamp value.

 FieldTransform::SetToServerValue setValue(FieldTransform::REQUEST_TIME);
 FieldTransform::FieldTransform fieldTransforms(fieldPath, setValue);

In case of array, we can't access the map or any field type inside the array i.e. no field path available for array.

Then you can't set the server timestamp to the field inside the array.

You have to provide your timestamp value in your map value manually instead of setting server timestamp.
