Absolute and Relative time fields could not be converted to seconds without converting to string and parsing to number. Fixed conversion in generated code that was subject to precision loss Usage: f=Field.new("frame.delta_time") delta=f().value:tonumber() Change-Id: I6ef91c6238a6c2ed9adf6cae03f8913f0a09332e Reviewed-on: https://code.wireshark.org/review/22316 Petri-Dish: Stig Bjørlykke <stig@bjorlykke.org> Tested-by: Petri Dish Buildbot <buildbot-no-reply@wireshark.org> Reviewed-by: Guy Harris <guy@alum.mit.edu>
