When typing this Q I found several other posts around this, looks like it's pretty unanswerable 
I'm posting this question on the back of a SO post over here.
I'm running rstudio in a docker container rocker/tidyverse.
Simple r block:
strtime_to_dt <- function(x) {format(strtime_to_dt(x), "%F %H:%M:%OS3")}
v1 <- c("1605859226452", "1605859226461", "1605859248803", "1605859261112", "1605859283839", "1605859471370")
format(strtime_to_dt(v1), "%F %H:%M:%OS3")
Error: C stack usage 7972180 is too close to the limit
Goal it to get datetime vector returned to the millisecond.
