Change DateTime to Unix timestamp in DataFactory Activity - azure-storage

Question

I am trying to copy Azure tables from one storage account to another storage account. But while doing this copy i want to change a column's datetime value to Unix Timestamp.
I am using Azure DataFactory Copy Activity. If i specify InitialDate column type as Int64 in output dataset then i am getting error that cannot convert datetimeoffset to Int64.
"activities": [
{
"type": "Copy",
"typeProperties": {
"source": {
"type": "AzureTableSource"
},
"sink": {
"type": "AzureTableSink",
"azureTablePartitionKeyName": "PartitionKey",
"azureTableRowKeyName": "RowKey",
"writeBatchSize": 0,
"writeBatchTimeout": "00:00:00"
},
"translator": {
"type": "TabularTranslator",
"columnMappings": "PartitionKey:PartitionKey,RowKey:RowKey,Timestamp:Timestamp,InitialDate"
},
"parallelCopies": 32,
"cloudDataMovementUnits": 32
},
"inputs": [
{
"name": "InputDataset-3tk"
}
],
"outputs": [
{
"name": "OutputDataset-3tk"
}
],
"policy": {
"timeout": "1.00:00:00",
"concurrency": 1,
"executionPriorityOrder": "NewestFirst",
"style": "StartOfInterval",
"retry": 3,
"longRetry": 0,
"longRetryInterval": "00:00:00"
},
"scheduler": {
"frequency": "Day",
"interval": 1
},
"name": "Activity-0-Test->Test"
}
]
Is there anyway i can change InitialDate column values to UnixTimestamp (Int64) while copying to output dataset ?
Are there any other translators other than TabularTranslator ? I couldn't find any info in web.

If I understand correctly, you want to change column value during copy data from one storage table to another storage table with DataFactory. Base on my experience, it is not supported by DataFactory Copy Activity currently.
In my option, there is a workaround is that we could use the Azure scheduled webjob to do that. In the WebJob could use Azure storage SDK to copy table record and the change column value then insert into another table.
