PR Summary

• Introduction of a New Date Library
  Our developers have incorporated a new date library called 'Carbon' in the file BulkAssetsController.php. This allows us to handle dates and times in a more efficient and more accurate way.

• Setting Asset End-of-Life Date
  The developers have added conditions to automatically assign an end-of-life date (EoL date) to assets. This helps in effective asset management by predicting when the assets will no longer be useful or functional.

• Handling Null Asset End-of-Life Dates
  A new feature has also been included that will assign a null value to an asset's EoL date when certain conditions are met. This ensures effective data handling and accuracy when an asset's EoL date cannot be predicted or is not available.

Hey @Robert-Azelis, I'm not turning this down right now and at first glance it looks great, but I'm right in the middle of writing some tests and some possible changes on the BulkAssetsController (we keep working on the same files at the same time!).

More importantly, we're right in the middle of our final push to get v7 released, so I'll keep this open and get back to it (and your other PR) as soon as we've got that all out the door.

Sorry for my lack of communication about it and thanks for your patience!

@spencerrlongg given v7 and your changes, is this still valid?
