How to configure a Time Category to calculate as decimal instead of time

In Jarrison Time, Time Categories are used to store values for time. Time Categories can be set to display as decimal, however for calculation purposes it may be required to work with an actual decimal value. Time Categories can be set to always calculate and display as decimal format. Below is the step required, and a brief example of how a decimal Time Category could be used.

1) To change a Time Category to a decimal storage holder, navigate to Setup > Day Programs, and select or add a suitable Time Category.


2) Tick the Is Decimal checkbox underneath, and Save. The Time Category is now ready to be used as decimal.

3) The remaining steps detail the use of a decimal Time Category, used to calculate daily NT pay. First navigate to Setup > Custom Fields, and add a field for Rate.


4) Then locate an individual to test on, open their Employee Details, Personal1 tab.

5) Enter an hourly pay rate in the new custom field. (Note: this step could be performed in bulk via Multiple Action, or CSV file import)

6) Then navigate to Setup > Day Programs and select a Day Program to apply the calculation on.

7) Apply a formula to calculate rate by multiplying earned NT by the custom Rate field, storing the result in the new decimal Time Category. Then Save. (Note this formula would need to be applied accordingly on every Day Program that should contribute a result)


8) Results can now be tested and checked from Daily Details.

The person earned 8 hours NT, at a rate of 84.20 an hour, resulting in 673.60 NT Pay.

Note that all JT users in a system should be set to the same decimal symbol in Windows Regional settings to avoid potential confusion.

Glossary of Terms

.Net Framework

(known as “dot net”) .Net is a software development framework for building and running applications on Windows.

Access Control

Access control refers to the restriction of people’s ability to clock on biometric devices based on location and/or time. Advanced access control includes anti-passback and zone sequencing.

Access Groups

Access Groups in Jarrison Time are combinations of Devices and Time Zones, used to determine on which devices and at which times members of the Access Groups may clock. Access Groups also facilitate restrictions based on too much or too little clocking in specified time-frames.

Access Groups can by synchronized or imported by Third-Party Import, or by users.

Access Zone

In Jarrison Time an Access Zone is how devices are grouped together to form logical zones for the purposes of access control. The option is available with the JT Live module.

Adjustments (Manual Adjustments)

Adjustments are the method of covering absence of time by employees in Jarrison Time. Examples of adjustments would be Annual leave and Sick leave. Adjustments are typically applied by a user via Daily Details as needed, or can be imported from file. It’s very important that Adjustments are correctly configured and applied as paid or unpaid. (Unpaid will result in Short Time.)

Anti Passback

Anti Passback is a form of access control where people are restricted from clocking on the device most recently clocked on, until they have clocked at another device.

Approval Bypass

Approval Bypass is a feature of Jarrison Time Approvals that allows for the first approval tier to be approved without any exceptions being cleared.


Approvals are a system-wide setting that forces users to correct Exceptions and then lock periods from further editing, ready for submission to payroll.

Jarrison Time allows for up to three tiers of Approvals: Daily Summary (timesheet), Pay totals, Department totals. Starting at timesheet level, each tier needs to be approved before the next one can process.


An Area in Jarrison Time refers to a GPS location with a set radius, which designates a permitted T&A clocking area for JT Clock users.

Area Schedule

The Area Schedule is used in conjunction with JT Clock to determine where JT Clock users should clock on a given day.


Authentication in the context of access control or T&A is the means by which a person identifies themselves to biometric devices for clocking purposes.


In Jarrison Time it is possible to allow employees to earn unapproved overtime when working additional hours. The unapproved time must then be authorized (to change to payable OT) or declined by a user. Authorization categories are setup so the system knows where to send approved or declined time.

Biometric Device (Reader)

A biometric device is a type of device (also known as a reader), usually wall-mounted but can be handheld, used to authenticate a person’s identity by recognizing some part of their body. Jarrison Time is directly compatible with a wide range of biometric devices covering the following means of authentication: Fingerprint, Face, Palm. Tags and PINs can also be accepted if the device supports it.

Bouncing (Shift Sensing)

Bouncing is a system-based method of assigning Day Programs to employees based on their clocking times. The selection of Day Programs the system can apply and when to apply them needs to be configured.
