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

[Christofer Bogaso]

Hi,

Below is my code :

library(zoo)
Dat1 = structure(c(17890, 17770.01, 17600, 17593, 17630.01), index =
structure(c(1512664740,
1512664800, 1512664860, 1512664920, 1512664980), class = c("POSIXct",
"POSIXt"), tzone = "America/Los_Angeles"), class = "zoo")
Dat2 = structure(c(15804.28, 15720.61, 15770, 15750, 15770), index =
structure(c(1512664740,
1512664800, 1512664860, 1512664920, 1512664980), class = c("POSIXct",
"POSIXt"), tzone = "America/Los_Angeles"), class = "zoo")

merge(Dat1, Dat2)

                        Dat1     Dat2
2017-12-07 22:09:00 17890.00 15804.28
2017-12-07 22:10:00 17770.01 15720.61
2017-12-07 22:11:00 17600.00 15770.00
2017-12-07 22:12:00 17593.00 15750.00
2017-12-07 22:13:00 17630.01 15770.00


So, after merging the TZ of the original series got changed.

Appreciate if someone points what went wrong
