This can be added as Non Billable time entries.
To add a Non Billable time entry, go to Timesheets main menu, and enter a time entry there with no Job assigned to it. On the note section, you can include details of the reason for the entry, i.e. Lunch, Travel, Sick Leave, Annual Leave etc.
You can create special Billing Rates to use in these instances to further categorise the entry if needed.
