Hello dear @ABraun.
Does this mean that when we download the Sentinel-1 image we need to convert it?

For example, I Downloaded the Sentinel-1 image and Time is (00:23:18) this time need to convert to local time?

yes, you can convert it to local time using the map here, for example: https://en.wikipedia.org/wiki/Coordinated_Universal_Time

Thanks a lot.
