Earnings release dates and time (BMO/AMC) using R Eikon

basicj

I am trying to retrieve historical earnings release dates and time using R. At the moment I use the package https://github.com/CharlesCara/DatastreamDSWS2R/blob/master/README.md to connect to Eikon Datastream.

Here is the code I use:

# Get quantmod

if (!require("quantmod")) {
install.packages("quantmod")
library(quantmod)
}

install.packages("devtools")

require(devtools)

install_github("CharlesCara/DatastreamDSWS2R")

options(Datastream.Username = " ************ ")

options(Datastream.Password = " ************ ")

require("DatastreamDSWS2R")

require("xts")

## create a connection

mydsws <- dsws$new()

IBES <- mydsws$timeSeriesRequest(instrument = "US0378331005", datatype = "EPSISURDTE",
startDate = "1990-01-01", endDate = "2018-01-31" )

IBES<-as.Date(unique(IBES$US0378331005))

The problem is that with this code I only get the dates without the information if the earnings release is After Market close or before maket open.

I need this information (AMC/BMO) and don't fine the right datatype to get it.

Does anybody know how to retrieve using R (NOT EXCEL) the historical information about AMC/BMO???

Thank you in advance for your help!
