Add PCICt date format management

I am replying on behalf of Katie and I, as I am running the airGR package as part of our ongoing research. The error comes when using POSIXct dates with 360-day years. POSIXct does not accept the 29th and 30th February as dates, so gives them NA values. When I use this with CreateInputsModel I get the error:

“Error in CreateInputsModel(FUN_MOD = get(paste0("RunModel_", model)),  : 
  'DatesR' must not include duplicated values”

I have tried running CreateInputsModel with PCICt dates (which accepts 360 day years), but this gives the error:

“Error in CreateInputsModel(FUN_MOD = get(paste0("RunModel_", model)),  : 
  'DatesR' must be defined as 'POSIXlt' or 'POSIXct'”

I have run the model successfully using a dummy set of POSIXct dates, and then converted back to the original dates at the end of the process. Is this approach acceptable? I have also seen your previous conversation with Katie, but could not quite understand the solution. Do you suggest duplicating the 28th February data to act as in-fill data for the 29th and 30th February?
