Android Question Need to know what time it is EST with DST accounted for

[BumForALiving]

No matter where my app is run in the world, I need to know what time it is EST.

When setting the time zone to EST using DateTime.SetTimeZone(-5) the time is off by an hour which must be related to daylight savings time.

How do I properly detect EST accounting for DST?

 

[Erel]

EST is always GMT-5. EDT is always GMT-4.

Do you want to show the current time in New York (for example)?

 

[BumForALiving]

Correct. So DateTime.SetTimeZone(-4) will always give me NY time?

 

[Erel]

No. This will set the time zone to -4.

You can use this code:

Sub Activity_Create(FirstTime As Boolean)
   SetTimeZone("America/New_York")
   Log(DateTime.Time(DateTime.Now))
End Sub

Sub SetTimeZone(id As String)
   Dim r As Reflector
   Dim idTz As Object = r.RunStaticMethod("java.util.TimeZone", "getTimeZone", Array As String(id), _
     Array As String("java.lang.String"))
   r.RunStaticMethod("anywheresoftware.b4a.keywords.DateTime", "setTimeZoneInternal", _
     Array As Object(idTz), Array As String("java.util.TimeZone"))
End Sub

That works.

Once again, thank you Erel!
