Integrate community call data?

[poikilotherm]

As the community calls are now happening at two different times, could it be an interesting option to add best fit call-in times to installations? Or provide timezones and a popup when both calls are happening in that timezone?

That might be a nice addition to https://dataverse.org/community-calls

(Minimal example with Leaflet plugin: https://dj0001.github.io/Leaflet.timezones)
