How to change only Date without changing Time in DateTimeOriginal tag

Hello!
Need a help in solving some problem!
How to change only Date without changing Time in DateTimeOriginal tag?

[StarGeek]

Can you give an example of exactly what you want to do?  Do you want to shift the date by a set time. For example, shift the days ± a few days?  Or set it to a specific date no matter what the current value is?

Thanks for the quick response!

Set it to a specific date no matter what the current value is!

Example:
filename_1.jpg (DateTimeOriginal: 2014:05:08 17:22:11)
filename_2.jpg (DateTimeOriginal: 2008:06:10 10:17:09)
filename_3.jpg (DateTimeOriginal: 2012:03:24 15:05:48)

Need to get this result
filename_1.jpg (DateTimeOriginal: 2014:05:08 17:22:11)
filename_2.jpg (DateTimeOriginal: 2014:05:08 10:17:09)
filename_3.jpg (DateTimeOriginal: 2014:05:08 15:05:48)

See this post. 

That gives examples for three tags.  Just keep the ones you want.
