I have timeseries data at 15min increments, however, due to failed sensors, loggers, or power issues, the dataset is missing some of the time steps (from hours to months). As a result, the dateset is not continuous. How would you fill in the missing dates (missing time steps)? Missing data is no issue here (it will be filled with NANs); I'm only concerned with time increments. The premise is to generate a continuous dataset, in terms of time steps. The dataset is in MM/DD/YYYY HH:MM format. I could fill in the missing dates manually, however, there are 5.5*10^5 time steps in the dataset.
Any help would be greatly appreciated. Thanks, -Maciek
