Help with timezone display?

Recommended Posts

Magikarp7

Hi guys! Can someone help me display the time on a specific time zone represented by a label?

$Form2 = GUICreate("Form2", 405, 294, 142, 192)
$Label1 = GUICtrlCreateLabel("Label1", 48, 48, 36, 17)  ;EST
$Label2 = GUICtrlCreateLabel("Label2", 48, 88, 36, 17) ;PST etc etc.
GUISetState(@SW_SHOW)



Sorry I'm still a beginner on this language but I'm glad the people in this community are helpful!
I know I have to use the _Date_Time_GetTimeZoneInformation function but I can't seem to understand it clearly. I want to display the PST, MST, CST, and EST time in a Label or an Inputbox if possible. and can I do it in a 12 Hr format? with the AM/PM label?

any help would be appreciated. or any small examples. Cheers!

Well, that was educational... for me anyway :)

You need to do some work:

Check the summer time / winter time transition date.

Check the whole thing is sane for winter - summer transitions for your local machines.

Check I have correctly defined all the timezone stuff, I'm not in North America, so I just put down some values from memory to test it ran.

#include <GUIConstantsEx.au3>
#include <Date.au3>

Opt('MustDeclareVars', 1)
Opt("GUIOnEventMode", 1)

Global $Form2 = GUICreate("Form2", 405, 294, 142, 192)
Global $Label1 = GUICtrlCreateLabel("Label1", 48, 48, 172, 17)  ;EST
Global $Label2 = GUICtrlCreateLabel("Label2", 48, 88, 172, 17) ;PST etc etc.
GUISetOnEvent($GUI_EVENT_CLOSE, "GUIExit")
GUISetState(@SW_SHOW)

Global Const $Tag_Struct = "struct; long Bias;wchar StdName[32];word StdDate[8];long StdBias;wchar DayName[32];word DayDate[8];long DayBias; endstruct"
Global $EST_info = DllStructCreate ($Tag_Struct)
DllStructSetData ($EST_info, "Bias", 300)
DllStructSetData ($EST_info, "StdName", "Eastern Standard Time (Winter)")
DllStructSetData ($EST_info, "StdDate", _Date_Time_EncodeSystemTime (10, 5, 0, 3, 0, 0))
DllStructSetData ($EST_info, "DayName", "Eastern Standard Time (Summer)")
DllStructSetData ($EST_info, "DayDate", _Date_Time_EncodeSystemTime (3, 5, 0, 2, 0, 0))
DllStructSetData ($EST_info, "DayBias", 300)

Global $PST_info = DllStructCreate ($Tag_Struct)
DllStructSetData ($PST_info, "Bias", 480)
DllStructSetData ($PST_info, "StdName", "Pacific Standard Time (Winter)")
DllStructSetData ($PST_info, "StdDate", _Date_Time_EncodeSystemTime (10, 5, 0, 3, 0, 0))
DllStructSetData ($PST_info, "DayName", "Pacific Standard Time (Summer)")
DllStructSetData ($PST_info, "DayDate", _Date_Time_EncodeSystemTime (3, 5, 0, 2, 0, 0))
DllStructSetData ($PST_info, "DayBias", 480)

Global $System, $EST, $PST

While 1
  $System = _Date_Time_GetSystemTime()
  $EST = _Date_Time_SystemTimeToTzSpecificLocalTime($System, DllStructGetPtr ($EST_info))
  $PST = _Date_Time_SystemTimeToTzSpecificLocalTime($System, DllStructGetPtr ($PST_info))
  GUICtrlSetData($Label1, _Date_Time_SystemTimeToDateTimeStr($EST))
  GUICtrlSetData($Label2, _Date_Time_SystemTimeToDateTimeStr($PST))
  Sleep(100)
WEnd

Func GUIExit()
  GUIDelete()
  Exit
EndFunc

Hopefully you can see how it is easy to add additional time zones.

Edit: Hmm, I thought about this some more and I think you will need to check that $System is being calculated correctly - I'm in GMT so this is not a problem for me and I can't easily test whether it converts a non-zero region time to UTC ok... just saying in case it does not work for you, this is probably why.
