There is a known issue of an extra hour gained for a machine setting time
zone to "Europe/London", regardless of the time zone associated with
the POSIXct inputs. It relates to anytime and Boost. Use Sys.timezone()
to check if the system time zone is "Europe/London". It would be recommended to
change the global environment "TZ" to other equivalent names: GB, GB-Eire,
Europe/Belfast, Europe/Guernsey, Europe/Isle_of_Man and Europe/Jersey as
documented in ?Sys.timezone()
, using Sys.setenv(TZ = "GB")
for example.
