Would like to set the Eastern time zone for EM logs. It seems like ET, EST and EDT not working. IST and CST seems to work good as string.
Please try the following in ./config/logback-em.xml file.
<variable name="LOG_PATTERN" value="%d{yyyy-MM-dd HH:mm:ss.SSS, America/New_York} %5p %pid --- [%t] %logger{44} : %m%n%ex"/>
