R version date is wrong when running sessionInfo()

When running sessionInfo() or devtools::session_info() the R version date for 3.6.1 is listed as 2017-01-27 when it should be 2019-07-05.

##  version  R version 3.6.1 (2017-01-27)

I noticed that the session info R for Data Science has the same wrong date for R version 3.5.2:

#>  version  R version 3.5.2 (2017-01-27)

Not sure if this is a Travis or Ubuntu or something else issue but thought I’d mention just in case.
