I have a data frame that contains dates, but when I use as.POSIXlt() I lose
the hours on all records. I traced this down to a particuar hour which
causes the issue...
> as.POSIXlt('2004-10-31 02:00:00')
[1] "2004-10-31"
> as.POSIXlt('2004-10-31 03:00:00')
[1] "2004-10-31 03:00:00"
How do I tell as.POSIXlt() to ignore daylight savings and just convert to a
time as is? I've read about the 'isdst' but it is still unclear what to do.
This is a cleaned up date field that I received so adjusting the date itself
is not possible.
Thanks in advance.
