How do i change time on my lenovo tab to pacific time

Clock should have the ability for you to change setting to Eastern zone

Setting The Time, The First Time IMPORTANT: The first time you connect your new SmartSet clock radio to the AC outlet the internal computer will automatically set the time correctly for the Eastern Time Zone, which is the initial default setting. The display will scan for a few seconds and then show the correct Day and Time in the Eastern zone. If you live in the Eastern Time zone, there's nothing else to do. Your clock is set correctly and running. If you do not live in the Eastern Time zone you must change the default zone display to your own zone. You only do this one time and the SmartSet will remember the new default zone setting and will always return to that setting after a power interruption. There are 7 time zones programmed into your SmartSet clock radio as follows: ZONE 1 - Atlantic Time ZONE 2 - Eastern Time (Default Setting) ZONE 3 - Central Time ZONE 4 - Mountain Time ZONE 5 - Pacific Time ZONE 6 - Yukon Time ZONE 7 To c h a n g e t h e d e f a u l t t i m e z o n e d i s p l a y, depress the TIME ZONE button. The number "2" will appear on the display indicating that the default zone is ZONE 2, Eastern Time. Hold theTIMEZONE button and then press either the or buttons your own time zone appears on the display, then release the buttons.

Select The Time Zone - For Sentry Self-setting Atomic Clock (ATC - 10)
The default time zone is Pacific zone.
1. In the normal time mode, press the MODE key to enter the alarm time mode.
2. Press the SET key to change the time zone.
each press of the SET key will move the time zone back one hour
P= Pacific M=Mountain C=Central E=Eastern
3. Press MODE key when correct Time Zone is highlighted.

I think the Instructions may tell you to use the ADJUST key instead of the SET key.
ADJUST key does not work for TIME ZONE change, SET key works.
This will set your clock to your chosen Time Zone for normal time.
