I try to apply Pitest to an older project that relies on timezone settings. Some tests are specifically for daylight-saving issues, when certain days in a year have more or less than 24 hours in local time. I cannot change the code or the tests. These tests fail with Pitest but run fine otherwise. From what I see, JUnit/Surefire takes

Converting Time Zone to GMT values in Java 11
We keep time zones of the cities in our config table using ID of Time Zone values as Europe/London, Asia/Tokyo, etc. However, when selecting time zones from the list, user needs to see the GMT values for these time zones and we want to display Display Name of Time Zone Options as (UTC+00:00) Dublin, Edinburgh, Lisbon, London rather than Europe/London.
Store date in AEST timezone in database
We have two tables in oracle db as below, TableA => Column DateA (type DATE) TableB => Column DateB (type DATE) DateA column in TableA has dates stored in UTC. DateB column in TableB has dates stored in AEST. When I checked the code (its in java) where the dates are being stored in these tables, both are just instantiating
Convert LocalDateTime UTC to Europe/Rome gave me wrong result
I tried to search for the same problem but didn’t find what I’m doing wrong. I need to convert a UTC LocalDateTime to a Europe/Rome LocalDateTime. I’m following this approach that I found on SO but I’m having a wrong result: I’m expecting the “converted time” to be 17:00 but I’m having this result. Thanks Answer I’m expecting the “converted
How to ensure that java system property `user.timezone` is explicitly specified?
I want to be sure that my Java program is always run by explicitly specified user.timezone property. I pass -Duser.timezone=XXX as a command-line setting. However, when I omit that system property at all, and then in my program I check the value of System.getProperty(“user.timezone”), it is not null, instead, it contains the system timezone. So, I can’t terminate my program,
Getting the UTC timestamp in Java
An old Stack Overflow posting suggests that the way to get the UTC timestamp in Java is the following: Unfortunately this does not work for me. I have a very simple program (reproduced below) which demonstrates different behavior. On Windows: the time is the local time and it is labeled with the offset with GMT On Linux: the time is
Calculate time from date taken with different timezone
I have a MySQL database which is storing a datetime value, let’s say 2020-10-11 12:00:00. (yyyy-mm-dd hh:mm:ss format) The type of this date (in mysql) is DATETIME When I retrieve this data in my controller, it has the java 7 type “Date”. But it adds a timezone CEST due to my locale I suspect. Here I already find confusing that
How do I force a Spring Boot JVM into UTC time zone?
I saw Force Java timezone as GMT/UTC I tried mvn spring-boot:run -Dexec.args=”-Duser.timezone=GMT” mvn spring-boot:run -Dexec.args=”-Duser.timezone=UTC” user.timezone=UTC in config/application.properties user.timezone=GMT In the pom.xml: mvn spring-boot:run -Dspring-boot.run.jvmArguments=”-Duser.timezone=UTC” But it prints out sun.util.calendar.ZoneInfo[id=”America/New_York”,offset=-18000000,dstSavings=3600000,useDaylight=true,transitions=235,lastRule=java.util.SimpleTimeZone[id=America/New_York,offset=-18000000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=3,startMonth=2,startDay=8,startDayOfWeek=1,startTime=7200000,startTimeMode=0,endMode=3,endMonth=10,endDay=1,endDayOfWeek=1,endTime=7200000,endTimeMode=0]] Spring Boot 1.5.19, Java 8 Answer Use spring-boot.run.jvmArguments property if you want to pass JVM options from Maven Spring Boot Plugin to forked Spring Boot application: This is be equivalent
Why does the java.time.Clock has zone information?
Why does java.time.Clock has zone information? From the Clock you only can get an Instant when calling the instant() method – which is a time without zone info. Is the only purpose to have the zone available in the clock to e.g. create a ZonedDateTime like this? ZonedDateTime.ofInstant(clock().instant(), clock().getZone()) Wouldn’t it then make sense to have a method zonedDateTime() in
