how to handle date comparison in Java during daylight saving?-CodePudding

Not to run code at 5:30 Morning in Summer and not to run code on 6:30 in winter.

In Java Code, Applied following

scheduler (30 mins)
if(time.equals(5:30))
///exit code

but now winter comes and we need not not run it at 6:30 AM

How to handle this use case for daylight saving areas?

CodePudding user response：

I am not sure what's the actual library you are using here, so I can't provide a code example, but basically you could use LocalDate or something similar and configure it in your timezone. This would know about the daylight savings.

CodePudding user response：

You can use TimeZone's inDaylightTime() method to determine if day light saving is applied or not e.g.

if(TimeZone.getTimeZone("US/Alaska").inDaylightTime(new Date())){

   // when daylight is true

}
else{
   // Code when daylight saving is false

}

For machine's default time zone, you can check like

TimeZone.getDefault().inDaylightTime(new Date())
