Hi, Provided (1) you have a single field in your CSV data that is consistently formatted in local time and (2) you define an appropriate format string for your CSV date-time data (the raw_datetime_format config option) in your import config file wee_import should be able to decode the CSV date-time field and construct the appropriate epoch timestamp irrespective of daylight saving. The 'conversion' to/from daylight saving is all handled by the underlying python datetime and time modules.
That being said I would suggest a standalone import of a month or two that covers a daylight savings changeover and confirm that you are getting the correct/expected results.
