[Storage] --if-unmodified-since The condition specified using HTTP conditional header(s) is not met #5286
Description
I have a storage account with a storage container called "backups".
when the storage container is empty (no blob backup files in it) this command works:
az storage blob delete-batch --source backups --if-unmodified-since `date -d "1 month ago" '+%Y-%m-%dT%H:%MZ'`
[]
the command above deletes the files that were not modified since the last month, and it works as expected.
if I upload one blob backup file into the storage container and run the same command, it errors:
az storage blob delete-batch --source backups --if-unmodified-since `date -d "1 month ago" '+%Y-%m-%dT%H:%MZ'`
The condition specified using HTTP conditional header(s) is not met.
<?xml version="1.0" encoding="utf-8"?><Error><Code>ConditionNotMet</Code><Message>**The condition specified using HTTP conditional header(s) is not met.**

Another example:
I have uploaded two blob files into the same storage container (now the storage container is not empty, it contains the two blob backup files)
az storage blob delete-batch --source backups --if-unmodified-since `date -d "2 minutes ago" '+%Y-%m-%dT%H:%MZ'`
The condition specified using HTTP conditional header(s) is not met.
<?xml version="1.0" encoding="utf-8"?><Error><Code>ConditionNotMet</Code><Message>**The condition specified using HTTP conditional header(s) is not met.**
It errors but it has actually deleted one of the backup files that I uploaded 4 minutes ago.
It would be great to fix that error message since the delete operation is actually working properly. Thanks
