Change the legend's timestamp format in R dygraphs

I'm charting a time series with dygraphs in R like the following:

library(dygraphs) library(htmlwidgets) library(data.table)  now <- Sys.time() dataset <- data.table(time = as.POSIXct(now+1:10),value = 1:10) d <- dygraph(dataset)  

The date format displayed in the legend depends in the machine locale and I cannot leave it fixed.

The labels of the x axis can be formatted as follows:

valueFormatter<-"function formatValue (ms) {                 return ms.toISOString(); }"  d <- d%>%dyAxis("x", axisLabelFormatter=JS(valueFormatter)) 

However, I don't know how to do it for the legend.

Similar to axisLabelFormatter there is legendForamtter. See for examples:
