<cfscript>
startTime = parseDateTime("2022-01-02 03:04:05", "yyyy-mm-dd HH:nn:ss", "Europe/London")
upTime = startTime.diff("s", now())

writeDump([
    startTime = startTime,
    upTime = upTime
])

https://trycf.com/gist/74e8f4b5563e90f56a81d411d02e332f/lucee6-beta?theme=monokai Lucee 5: the diff is positive, eg: 43246273 Lucee 6: the diff is negative, eg: -43246306 Actually it's probably this: https://luceeserver.atlassian.net/browse/LDEV-2044 ? So a bug fix.

yup, looks like it, flagged as breaking-change
