Daylight saving-time not parsing

[ruria]

Version: 5.6.3
Operating System: CentOS 7
Config File (if you have sensitive info, please remove it):
input { stdin {} }
filter {
date {
match => [ "message", "yyyy-MM-dd'T'HH:mm:ss,SSS" ]
target => "MyParsedDate"
}
}
output { stdout { codec => rubydebug }}

Sample Data:
2017-03-26T02:59:33,492
2017-03-26T12:59:33,492

Steps to Reproduce:
Launch logstash.
Logstash fails to date parse first line of data.

we can narrow down this. The error rises only during daylight saving-time. So 2017-10-26 between 02 to 03 , 2016-10-25 between 02-03 and so on... automatic daylight saving-time adjustment is on, and we´re in GMT +2 time zone.
