Flextime calculation is part of Severa's Business, Platinum and Enterprise editions.
Flextime adjustments are manual changes to a user's flextime. Flextime adjustments are made through the user's profile by opening Settings > User management. To add a flextime adjustment, go to Employee settings > Flextime and click Add flextime adjustment.
Add flextime by entering a positive hour quantity,
or decrease flextime by entering a negative hour quantity.
In the Adjustment date field, specify the date to which you want to apply the adjustment.
