All-day events created by the device after the upgrade are modified

All-day events created by the device before the upgrade to the new EAS server after the upgrade are modified on the device in events starting at 8:00 am and ending at 6:00 pm.

Steps to reproduce:

• use the version 2.3.4.9 of z-push
• connect an android device via EAS
• create an "all day" event on the device and force synchronization
• the event is shown regularly both on the device and on the WebTop
• update the server with the new version 2.4.5.7 of z-push
• update the synchronization on the device

Expected behaviour:

• the "all day" event created previously remains unchanged both on the device and on the WebTop interface

Actual behaviour:

• the "all day" event created previously on the device is modified in an event that starts at 8:00 am and ends at 6:00 pm on the same day while it remains unchanged on the WebTop interface

NOTE:

A new event created "all day" from the device (after the update) and synchronized with the server, on WebTop appears not as an "all day" event but starting at 0:00 on the same day and ending at 0:00 of the following day (see image attached).
