After upgrading the client side Java to 1.8u281+, the database date and time display in the lower right corner of the client displays GMT time.
This occurs when the master's TZ time variable is set to use US/Pacific-New and the client side Java is using 1.8u281+. This is due to a change by Oracle in Java which US/Pacific-New Zone Name has been removed. This is noted in Java's release notes as followed.
Java 8 Update 281 (8u281)
Other notes: US/Pacific-New Zone Name Removed as Part of tzdata2020b Following the JDK's update to tzdata2020b, the long-obsolete files named pacificnew and systemv have been removed. As a result, the "US/Pacific-New" Zone name declared in the pacificnew data file is no longer available for use. See JDK-8254177
To resolve the issue, the master's TZ variable must be updated. It is recommend if using US/Pacific-New the timezone is changed to America/Los_Angeles.
