World Timer – GMT/UTC Multiple Time Zones watchface

If we are going to add a tag for timezone, it should include the 37 variants listed here (Time zone - Wikipedia link from your link) as well as summertime variants (and their start/end dates).

Otherwise it is just a curiosity.


The other approach would the top 200 cities of the world, with correct timezone and daylight/summer-time …

Yes. You are totally right @andrew.dowden - but it´s a nice curiosity and people like to play with their watches… :wink:

The old mechanic worldtimer watches didn´t have that features as well…

to set manual cities we can just add VAR Increment
try this tag: ((#VAR_1#%24)*15) from bezel cities Rotation :slight_smile:

hi, your work is very professional.
not easy for all people.
i ask:
if i want 2 times, example: London and New York ???
they have 6 hours of difference.
Db+6 or Db-6 don’t solve my problems, depending from the current time.
have you a idea to fix the formula ???
thank.

@un_ottico1965 Thank you… for personal use, we can use 0 utc time for time base

if (- offset) timezone, we can use this expression
$(#DUkZ#-offset)<0?((#DUkZ#-offset)+24):(#DUkZ#-offset)$:#DmZ#

if (+ offset) timezone, we can use this expression
$(#DUkZ#+offset)>24?((#DUkZ#+offset)-24):(#DUkZ#+offset)$:#DmZ#

feel free see inspect & learn how its work demo here

hope this help :slight_smile:

That expression is manual function for example:
Central European Standard Time
Time zone in Italy (GMT+1)
expression : $(#DUkZ#+1)>24?((#DUkZ#+1)-24):(#DUkZ#+1)$:#DmZ#

wherever we go country with different timezone,
I think it does not affect the change the time is still in the timezone in Italy (GMT+1)
if we want to change it, make sure our main time is 0 UTC :slight_smile:

very good tutorial!
now i need only to travel for the World
and see what happen!
but i think you have reason at all.
thank.

hi, can you check this face ???

i have lost a lot of time to fix the temperature, but the arrow stay
alway at the wrong side.

but…when i have fit the face on the watch, the temperature was right !!!

it’s a bug of the program ???

thank

Temperature -15 to 45 for °F or °C?
Try this expression: ((#WCT#*4)-90)
hope this help :slight_smile:

hi, temperature in Celsius.
listen:
why ((#WCT#*4)-90) ???
the 0 is at -45°
after i must place a +, because the arrow go from 0 (in the left side) to 100 (right side).
sorry, not 100 but 45.
+45° and -15° = 60° of course.
180° is the half-wheel.
180/60=3

this is the formula inside.
(-45+(#WCT#*3))

Try this expression: ((#WCT#*3)-45) or (#WCT#*3-45)
Hope its work… :slight_smile:

sorry, but like i have told before, the arrow don’t work on the program,
but work on the watch.



What temperature scales u use? °F or °C?
we need add Current Temp text for reference : #WCT#°#WM#
if Celsius °C , C to F try use this expression (((#WCT#*9/5)+32)*3-45)
if Fahrenheit °F, try use this expression (#WCT#*3-45)

thank you for your reply and show the pictures.
the problem is only in the program.
when you dress the watch, the
needle is in correct position.

I know this is an older post, but THANK YOU for this tag. I’ve been trying for a week to find the right code to show my home time zone when I travel and there’s always a glitch or catch to the ones I’ve found online. This one works perfectly!
Thanks!

Hi Ben,
I synced your G7 5 Time zone example to my watch and the results for the +3 and +8 UTC does not display correctly.

$(#DUkZ#+3)>24?((#DUkZ#+3)-24)’:’(#DUkZ#+3)$:#DmZ#
$(#DUkZ#+8)>24?((#DUkZ#+8)-24)’:’(#DUkZ#+8)$:#DmZ#

Note : I have included the quotes before and after the colon in your expressions above just to get rid of the emoji it generates.

The minutes portion shows fine though. Appreciate if you could please let me know if there is a roundabout to this expression.
Cheers,
Robson Ivan

Just want to let you know you can use the ` for that (before and after the expression):
$(#DUkZ#+3)>24?((#DUkZ#+3)-24):(#DUkZ#+3)$:#DmZ#
$(#DUkZ#+8)>24?((#DUkZ#+8)-24):(#DUkZ#+8)$:#DmZ#
