Date format extraction problem in XLS/XLSX

Currently TIKA/ManifoldCF 2.10 extracts dates from the attached file tis way:

2018.05.10 -> 10/05/18
2002.02.02 -> 2/2/2

We need this format:

2018.05.10 -> 2018-05-10

2002.02.02 -> 2002-02-02

This occurs only when the field type is date. When the field type is text then the output is fine.

Please help us with a recommendation with any settings in the pipeline (Tika configs, excel setting, OS local settings, etc.), or provide a fix.
