Changing Exponent of Tick Label possible?

Hello,

I have data that i plot in a timeline. The timestamps in my data is in microseconds.

Because of this my ticklabels are also in microseconds. However I would like my ticklabels to be in milliseconds (factor 1000) or maybe even seconds. So basically I would like to change the exponent of my ticklabels(without touching the data). Also see the Screenshot:

I already looked into tickformat but wasn’t able to come to a solution. Thanks for advance for help.
