[R] Zoo changing time-zone when I merge 2 zoo time series

[Eric Berger]

I found the following at
https://stackoverflow.com/questions/25269425/merge-zoo-removes-time-zone

library(xts)

merge2=function(x,y) {
  as.zoo(merge(as.xts(x), as.xts(y)))}

If you define the function merge2() as above then

merge2(Dat1,Dat2)

should be ok

HTH,
Eric
