The periodize function is used in this link.
There is a separate package called "periods" or "Period" or something ??
In which package could I find the function?
my intention is to reproduce the example:
x<-"2012-05-30 20:41:21 UTC"
(idt <- IDateTime(x))
(idate <- idt$idate)
(itime <- idt$itime)
ip_posix = as.POSIXct(periodize(idate, itime, "mins", 15), tz="UTC")
ip = periodize(idate, itime, "mins", 15)
to be
"20:45"
