The date level of confidence (DateLOC) provides an indication of how accurately the date associated with the trait or yield observation is known. tab:dateloc provides the values that should be entered in this field. If the event occurred at a level of precision not defined by an integer in this table, use fractions. For example, we commonly use 5.5 to indicate a one week level of precision. If the exact year is not known, but the time of year is, use 91 to 97, with the second digit to indicate the information known within the year.
