Bug timeSeries 270.76.1 - [ ] Message is from an unknown sender

[Daniele Amberti]

Yes, below You can find some code that make problem clear:


library(timeSeries)
MyTZ <- Sys.getenv("TZ")

Sys.setenv(TZ = "")
Sys.getenv("TZ")
# The problem is in timeSequence in a call to "strptime(charvec, isoFormat)" without the timezone.
# look for  [2008-03-30 02:00:00]
tseq <- timeSequence( from = '2008-03-29', to = '2008-03-31', by = "hour", zone = "GMT")
timeSeries(1:length(tseq), as.character(tseq),)

Sys.setenv(TZ = "GMT")
Sys.getenv("TZ")
# The problem is in timeSequence in a call to "strptime(charvec, isoFormat)" without the timezone.
# look for  [2008-03-30 02:00:00]
tseq <- timeSequence( from = '2008-03-29', to = '2008-03-31', by = "hour", zone = "GMT")
timeSeries(1:length(tseq), as.character(tseq),)

Sys.setenv(TZ = MyTZ)

Dear Daniele,

thanks for the report.

Have you noticed that the new version of 'fSeries' and 'fCalendar' are now
called 'timeSeries' and 'timeDate'. We changed their names to reflect
the internal changes of their respective classes.

The version number you used in your title is the one of the 'fSeries'
packages.

Could you please let me know if you have the same problem with the new
'timeSeries' package?

It would be very helpful if you could provide a minimal and reproducible
code to illustrate the problem.

Best regards,
Yohan
