To dual boot with Windows, it is recommended to configure Windows to use UTC, rather than Linux to use localtime. (Windows by default uses localtime)
It can be done by a simple registry fix: Open regedit and add a DWORD value with hexadecimal value 1 to the registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation\RealTimeIsUniversal
You can do this from an Administrator Command Prompt running:
C:\>reg add "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TimeZoneInformation" /v RealTimeIsUniversal /d 1 /t REG_DWORD /f

To delete a menu entry using efibootmgr
first list the current boot entries with sudo efibootmgr
Identify the boot number of the entry you want to delete, then use the command:
sudo efibootmgr -b XXXX -B
replacing XXXX with the boot number of the entry you wish to remove.
ADD
To add a menu entry using efibootmgr, use the following command format:
sudo efibootmgr -c -d /dev/sdX -p NN -L "Label" -l "\EFI\path\to\boot\file.efi"
where /dev/sdX is your disk, NN is the partition number,
“Label” is the name you want for the boot entry,
and \EFI\path\to\boot\file.efi is the path to the EFI executable.
!!! Make sure the path to the boot file is correct and uses backslashes, as required by the EFI specification!!!
