Writing Guidelines

Brief tips on writing documents:

1. Use YYYY-MM-DD and hh:mm:ss for date and time, 24 hr clock (ISO 8601)
2. Use The International System of Units (SI) for units (kg, m, °C..)
3. Use decimal comma (decimal dot is accepted) and space for thousands but never dot or comma for thousand (ISO 31)
4. When writing for an international audience, make a note of used notations - especially for date and time if not following international standard as above (ISO 8601).
