See user's point #1 of https://skyline.ms/announcements/home/support/thread.view?rowId=53519 (other points are split into other issues)

Probably should check with Agilent to verify this, find out actual supported precision, are there other models that do this, etc

User says "The Agilent 6495C can go down to a dwell time of 0.5ms (which we are currently running), however, skyline only allows integers in the Dwell time (ms) field when exporting a method. We changed it to 1 in order to export the method without an error, but if it is possible to allow lower dwell times in a future release, that would be helpful."

Skyline issues have moved to GitHub Issues at https://github.com/ProteoWizard/pwiz/issues
Issues will be ported as necessary for active work.
