> As per javadoc, the method FileStatus.getModificationTime() should return the
> time in UTC, but it returns the time in the JVM timezone.
> The issue origins in AzureBlobFileSystemStore.getFileStatus() itself, since
> parseLastModifiedTime() returns a wrong date. I have created a file in Azure
> Data Lake Gen2 and when I look at it through the Azure Explorer it shows the
> correct modification time, but the method returns -2 hours time (I am in CET
> = UTC+2).
> Azure Explorer last modified time:
> !image-2019-07-31-18-21-53-023.png|width=460,height=45!
> AbfsClient parseLastModifiedTime:
> !image-2019-07-31-18-23-37-349.png|width=459,height=284!
> It shows 15:21 CEST as utcDate, when it should be 15:21 UTC, which results in
> the 2 hour loss.
> DateFormat.parse uses a localized calendar to parse dates which might be the
> source of the issue.
