Hubitat is storing time entered in input preference as UTC without converting from hub timeZone to UTC

in code:

def fTime = timeToday(fromTime2, location.timeZone)
def tTime = timeToday(toTime2, location.timeZone)

ST input preferences:

fromTime2	time	23:00
toTime2	    time	05:00

ST log output:

rooms child ruleNo: 2 | fromTime2: 2017-12-31T23:00:27.000-0800 | fTime: Mon May 21 06:00:00 UTC 2018 | toTime2: 2017-12-31T05:00:27.000-0800 | tTime: Mon May 21 12:00:00 UTC 2018 | nowDate: Mon May 21 22:36:56 UTC 2018 | timeOfDayIsBetween: false

Hubitat input preferences:

fromTime2	time	22:00
toTime2	    time	06:00

Hubitat log output:

rooms child ruleNo: 2 | fromTime2: 2018-05-21T22:00:00.000+0000 | fTime: Mon May 21 22:00:00 UTC 2018 | toTime2: 2018-05-21T06:00:00.000+0000 | tTime: Tue May 22 06:00:00 UTC 2018 | nowDate: Mon May 21 22:31:26 UTC 2018 | timeOfDayIsBetween: true

so input time preferences like fromTime2 is stored as 2018-05-21T22:00:00.000+0000 without actually converting it to UTC. whereas ST correctly stores it in the hub local timezone.

thanks.

edit: currently having to hack it to get it to work right:

if (hT == _Hubitat)     {
    if (fromTime2)   fromTime2 = fromTime2.replace("+0000", "-0800")
    if (toTime2)     toTime2 = toTime2.replace("+0000", "-0800")
}
