By default, Excel stores dates as numbers with a format code that specifies date

<summary><b>Time Zones and Dates</b> (click to show)</summary>
Excel has no native concept of universal time. All times are specified in the
local time zone. Excel limitations prevent specifying true absolute dates.
Following Excel, this library treats all dates as relative to local time zone.

<summary><b>Epochs: 1900 and 1904</b> (click to show)</summary>
Excel supports two epochs (January 1 1900 and January 1 1904), see
["1900 vs. 1904 Date System" article](http://support2.microsoft.com/kb/180162).
The workbook's epoch can be determined by examining the workbook's
`wb.Workbook.WBProps.date1904` property:
```js
!!(((wb.Workbook||{}).WBProps||{}).date1904)

sheet-scoped name cannot collide with a workbook-scope name. Workbook writers
may not enforce this constraint.
