I think the OP is being vague by saying "time format" (wouldn't a small
reproducible example from the OP help right now)... if that is really another
character string laid out as described then you might have difficulty with time
zones for some values by converting to POSIXct first. If so, you can avoid the
double conversion by using sub:
timestr <- "2014-08-13 00:30:00"
result <- sub("^(\\d{4})-(\\d{2})-(\\d{2}) (\\d{2}):(\\d{2}):(\\d{2})$",
"\\1\\2\\3\\4\\5\\6", timestr )
