'''Important Rules''':
* The (meteorological) date format uses ''two digits for the year''. Edit this file using an editor that treats all fields as text (a text editor or a spreadsheet program that can be instructed ''not'' to recognise special field types).
* Times are in ''format hh:mm''
* Most value fields are in ''real number format x.y'' using your system decimal notation, a few (e.g. bearings, solar, humidity) are ''integers'' (see list of fields in file). Whilst an integer can be used for a real number field, decimals are not allowed in an integer field.
* If you insert a ''lowest or highest value'' into a day, where there was none before, insert a ''timestamp'' too, as a dayfile.txt row is only accepted by the Cumulus editor if a value and any related timestamp are either both present or both absent. (Use a timestamp of your rollovertime 00:00, 09:00 or 10:00 if you have not looked up the precise time).
* Nulls ',,' are not allowed in the line, so if you do not know the value for a particular field within the line, then type in a zero for integer values and an extreme with opposite value (e.g. -999.9 for a signed decimal maximum, and 999.9 for a decimal minimum) for decimal format (replace the full stops with your decimal separator).
