It has been quite a bit different in R-devel for a little
while. NEWS entries (there are more already, and more coming

I have no idea how to get readxl::read_excel to import a timestamp column in a
timezone. It is true that Excel has no concept of timezones, but the data one
finds there usually came from a text file at some point. Importing as character
is a feasible strategy, but trying to convince an
Right now as.POSIXlt.Date() is just

How expensive would it be to throw a warning when '...' is provided by
the user/discarded ??
Alternately, perhaps the documentation could be amended, although I'm
not quite sure what to suggest. (The sentence

Thanks for the clarification.

Liam,
I think I have failed to convey my main point in the last e-mail - which was
that you want to parse the date/time in the timezone that you care about so in
your example that would be

Is tidyverse time handling intrinsically broken? They have a standard practice
of reading time as UTC and then using force_tz to fix the "mistake". Same as
Python.

Alexandre,
it's better to parse the timestamp in correct timezone:

> as.POSIXct(as.character(foo), "Europe/Berlin")
[1] "2021-10-01 CEST"
The issue stems from the fact that you are pretending like your timestamp is
UTC (which it is not) while you want to
Hi R pkg developers,
We are facing a datetime handling issue which manifests itself in a
package we are working on.
In context, we noticed that reading datetime info from an excel file
resulted in different data depending on the computer we used.
We are aware that timezone and regional settings
