<paragraph role="paragraph" id="par_id3150437" xml-lang="en-US" l10n="U" oldref="170">$[officename] internally handles a date/time value as a numerical value. If you assign the numbering format "Number" to a date or time value, it is converted to a number. For example, 01/01/2000 12:00 PM, converts to 36526.5. The value preceding the decimal point corresponds to the date; the value following the decimal point corresponds to the time. If you do not want to see this type of numerical date or time representation, change the number format (date or time) accordingly. To do this, select the cell containing the date or time value, call its context menu and select <emph>Format Cells</emph>. The <emph>Numbers</emph> tab page contains the functions for defining the number format.</paragraph>
<paragraph role="paragraph" id="par_id3149720" xml-lang="en-US" l10n="U" oldref="183">In <emph>Tools - Options - $[officename] - General</emph> you find the area <emph>Year (two digits)</emph>. This sets the period for which two-digit information applies. Note that changes made here have an effect on some of the following functions.</paragraph>
<paragraph role="note" id="par_id3150654" xml-lang="en-US" l10n="U" oldref="185">When entering dates, slashes or dashes used as date separators may be interpreted as arithmetic operators. Therefore, dates entered in this format are not always recognized as dates and result in erroneous calculations. To keep dates from being interpreted as parts of formulas, place them in quotation marks, for example, "07/20/54".</paragraph>
