Incorporate timestamp in Logging Facade

[rohankasture]

The filter for timestamp is not working. I wrote below code for timestamp

if(filter.logsBefore!=null){
ZonedDateTime dateTime = Instant.ofEpochMilli(log.getTime())
.atZone(ZoneId.of("-5:00"));
tempLog.setTimestamp(dateTime);
if((dateTime.compareTo(filter.logsBefore))<=0)
logs.add(tempLog);
}
