Data traffic admin panel graph mismatch with data from GraphQL. + Timezone in GraphQL

Good day to all.
I have a question regarding the GraphQL Analytics API.
I’m trying to get daily or by minutes data transfer numbers. The docs say that total bandwidth is obtained by summing edgeResponseBytes. The data is very different from the readings of the data transfer graphs in the admin panel. GraphQL shows twice as much.
Tell me, please, maybe something is not taken into the admin panel charts?

And an additional question: is it possible to specify a timezone when querying in GraphQL?

Query:

                        viewer {
                            zones(filter: {zoneTag: $zoneTag}) {
