&dateSource "eats" tv-value in ditto template

[esszett]

In ditto v2.1.1 it was possible to retrieve both values of a date field:
[[Ditto? &dateSource='myunixtime' &dateFormat='%d.%m' … &hiddenFields='myunixtime' …]]
in the related ditto template I could retrieve
[+date+] //the formated value of myunixtime
[+myunixtime+] //the unformatted timestamp

In current Ditto v2.1.3 – [+myunixtime+] is empty. Is this the intended behaviour?

Ok – I've recognized that I can use [+tvmyunixtime+] in ditto template to retrieve the unformatted date-value.
