I have the following problem. I've got model data between the years 2006 and 2100, but every month has 30 days, that means the calendar format is 360_day. Is there the possibility, to change the calendar format in chron into this format? "This format" means, that I have 30 days for each month. With the method below, chron uses the normal calendar format.
The transformed timestamp starts at (12/Mar/2005 12:00:00) instead of the correct (1/Jan/2006 12:00:00) and uses the normal calendar format, which you can see, when you try out the code and use the subset.
time.reconf <- chron(time, origin = c(12, 1, 1949),format = c(dates = "dd/mm/yyyy", times = "h:m:s"))
the following data is a subset of time:

I've changed your time series into a normal vector
time <- c(20190.5, 20191.5, 20192.5, 20193.5, 20194.5, 20195.5,
20196.5, 20197.5, 20198.5, 20199.5, 20200.5, 20201.5, 20202.5,
20203.5, 20204.5, 20205.5, 20206.5, 20207.5, 20208.5, 20209.5,
...
20567.5, 20568.5, 20569.5, 20570.5, 20571.5, 20572.5, 20573.5,
20574.5, 20575.5, 20576.5, 20577.5, 20578.5, 20579.5)
Secondly, I've installed the PCICt package
install.packages('PCICt')
library(PCICt)
Here you can set the parameters on 360
cal <- "360_day"
Set the start day, to 2006-01-01
origin <- "2006-01-01"
seconds.per.day <- 60*60*24
And edit, the time series, If the structure, is the same as you've provided then (correct me if it is wrong), it should be correct to substract the first date, from all the other dates. thus : [ 20190.5, 20191.5, 20192.5, 20193.5 ...] will become [ 0 1 2 3 ... ] . thus, 0 is the same as 2006-01-01 and 1 is 2006-01-02 -- 2 is 2006-01-03 etc
ts.dat.days <- time - time[1]
origin.pcict <- as.PCICt(origin, cal)
ts.dat.pcict <- origin.pcict + (ts.dat.days * seconds.per.day)
print the series
ts.dat.pcict
