Centreon Engine version: 1.8.1

Centreon Broker version: 3.0.14

OS: CentOS 7

Additional environment details (AWS, VirtualBox, physical, etc.): VM on Hyper-V - Gen 2

Steps to reproduce the issue:

1. Create a time period
2. Enter 2 range separated by a semi colon: 7:00-11:00;17:00-20:00
3. Save

Describe the results you received:
The system accepts the values without issues. You can generate and push the configurations without issues

Describe the results you expected:
I expect an error as the semi colon should not be a valid character in those fields as per documentation: https://documentation.centreon.com/docs/centreon/en/2.8.x/configuration_guide/timeperiod.html
