DT = data.table(
t1 = as.POSIXct('2018-05-01 12:34:56', tz = 'UTC'),
t2 = as.POSIXct('2018-05-01 12:34:56', tz = 'Asia/Singapore')
)
DT
# t1 t2
# 1: 2018-05-01 12:34:56 2018-05-01 12:34:56
DT$t1
# [1] "2018-05-01 12:34:56 UTC"
DT$t2
# [1] "2018-05-01 12:34:56 +08"
The printed output makes t1 and t2 seem identical, but they're not.
The same problem applies to data.frames, to be fair:
setDF(copy(DT))[]
# t1 t2
# 1 2018-05-01 12:34:56 2018-05-01 12:34:56
Probably timezone printing should be on by default due to the above, but at least there should be an option.
