Review comment:
It's a bit confusing, but if you add a numeric vector to a POSIXlt
object then the result is a POSIXct. In the example below `a` does not have a
`"tzone"` attribute.
``` r
a <- strptime("2020-01-01", format = "%Y-%m-%d") + 1
class(a)
#> [1] "POSIXct" "POSIXt"
attributes(a)
#> $class
#> [1] "POSIXct" "POSIXt"
```
