Transactional replication of Date column from Sql Server 2012 SP4 to Azure Sql Database
converting my comment to answer ... 

Since you confirmed that the db compatiblity is 90 which is sql 2005

Run 

SELECT name, compatibility_level 
FROM sys.databases WHERE name = 'YOURDBName' 


and then you can use ALTER DATABASE [YOURDBName] SET compatibility_level = 110 -- 2012 version
