340 +Not so much a //bug// as much as "a thing that can happen if your SoloLite installation is corrupted". If you notice your data has large constant time offsets, you should suspect that the number of leap seconds has not been accounted properly. There is a file "smartsoloconfig.xml" that needs to be present in "C:\SmartSoloApps SoloLite" (e.g. the main program directory) that dictates the leap second offset for the last two data ranges. Since 2017-01-01, this is 18 seconds. At some point in the next few years it will be 19 seconds.
341 +
342 +If this file is missing, just create a new one structured like so, name it "smartsoloconfig.xml" and put it in your main program directory. Then, Reanalyze your data (tools > Reanalyze seismic data) and your data should have the correct time. You can also do this manually, if you want. The offset is 18 seconds precisely.
