1.4 Graveyard Shift Time Zone Example (Crossing Midnight)

This time zone example is designed for a graveyard shift employee, eligible to work from 11:30 P.M. to

7:30 A.M. Monday/Tuesday through Friday/Saturday.

The graveyard shift time zone is unique in that it starts in one day-of-the-week and ends in the next day-

of-the-week. To accommodate this, the time zone uses both the Start1/Stop1 and Start2/Stop2 cells to

cover the split in access times Tuesday through Friday.

1. Create a list of the days-of-the-week and the hours-of-the-day that an access group should have

access for this time zone. The following list describes this graveyard shift time zone.

• Monday – 11:30 to Tuesday – 07:30 hours (11:30 P.M. to 7:30 A.M.)

• Tuesday – 11:30 to Wednesday – 07:30 hours (11:30 P.M. to 7:30 A.M.)

• Wednesday – 11:30 to Thursday – 07:30 hours (11:30 P.M. to 7:30 A.M.)

• Thursday – 11:30 to Friday – 07:30 hours (11:30 P.M. to 7:30 A.M.)

• Friday – 11:30 to Saturday – 07:30 hours (11:30 P.M. to 7:30 A.M.)

2. From the Setup Timezones window (see Figure 3-1 on page 4 of this section), click on the

button. The day-of-the-week start fields and the time zone name field are cleared (see Figure 3-2 on

page 5 of this section).

3. Following the graveyard shift parameters given in Step 1 above, no access is allowed on Sunday.

Double-click in the Sunday Start1 cell and type N. The “Never” key appears in the cell setting this

time segment to never allow access on Sunday.

4. Double-click in the Monday Start1 cell and set the time to 23:30. Double-click in the Monday

Stop1 cell and set the time to 00:00. Monday access is limited to the hours between 11:30 P.M. and

Midnight.

5. Double-click in the Tuesday Start1 cell and set the time to 00:00. Double-click in the Tuesday

Stop1 cell and set the time to 07:30. Double-click in the Tuesday Start2 cell and set the time to

23:30. Double-click in the Tuesday Stop2 cell and set the time to 00:00. Tuesday access is split

between Midnight to 7:30 A.M. (to cover the end of the shift that began on Monday) and 11:30

P.M. to Midnight (to cover the beginning of the shift on Tuesday).

6. Repeat step 6 for Wednesday through Friday.

7. Double-click in the Saturday Start1 cell and set the time to 00:00. Double-click in the Saturday

Stop1 cell and set the time to 07:30. Saturday access is limited to the hours between Midnight and

7:30 A.M.

8. Click in the “Timezone Names” field and type Graveyard Shift TZ. The Setup Timezones

window should appear identical to Figure 3-5 on page 9 of this section. Any discrepancies can be

corrected by clicking on the cell or field and making the correction.
