DateConvert Function seems corrupt.

Status/Resolution/Reason: To Track//PRNeedInfo

Reporter/Name(from Bugbase): Michael Grant / ()

Created: 06/21/2018

Components: Tags

Versions: 11.0

Failure Type: Data Corruption

Found In Build/Fixed In Build: 11,0,14,307976 /

Priority/Frequency: Normal / All users will encounter

Locale/System: English / Windows 10 64 bit

Vote Count: 1

Problem Description:
Using DateConvert() inside DateAdd() creates a corrupt date/time object.
Please refer to this conversation

Steps to Reproduce:
Please refer to this conversation

Actual Result:
Evaluating two time objects gives unexpected results. Time 2 evaluates as earlier than Time 1

Expected Result:
Time 1 is later than Time 2.

Any Workarounds:
Wrapped DateAdd() function in ParseDateTime() to get a proper date/time object.



Correction: Under "actual result" it's actually Time 1 that evaluates as earlier than Time 2. In my test time1 was: {ts '2018-06-20 15:12:00'} and time2 was {ts '2018-06-20 09:00:00'} yet time1 evaluated as false when I did a GTE than time2. Sorry for the confusion.

@Michael We could see that you have used getDate() in the code, if you are setting anything specific to time zone or locale in this function please share with us, it would be helpful for us to repro. We tried the code below, we have used now() instead of getDate(). It worked as expected. <!--- Set date ---> <cfset thisDate = now()> <!--- Determine what flight they should see. ---> <!--- If it's after 9am and before 10pm ---> <cfif thisDate GTE CreateDateTime(DatePart("yyyy",thisDate),DatePart("m",thisDate),DatePart("d",thisDate),9, 0,0) AND thisDate LT CreateDateTime(DatePart("yyyy",thisDate),DatePart("m",thisDate),DatePart("d",thisDate),21 ,0,0)> <cfset d1 = "#DatePart('m',thisDate)#/#DatePart('d',thisDate)#/#DatePart('yyyy',thisDate)# 9:00:00"> <cfset d2 = "#DatePart('m',thisDate)#/#DatePart('d',thisDate)#/#DatePart('yyyy',thisDate)# 21:00:00"> <cfoutput>If it's after 9am and before 10pm</cfoutput> <!--- If it's after 10pm ---> <cfelseif thisDate GTE CreateDateTime(DatePart("yyyy",thisDate),DatePart("m",thisDate),DatePart("d",thisDate),21 ,0,0)> <cfset d1 = "#DatePart('m',thisDate)#/#DatePart('d',thisDate)#/#DatePart('yyyy',thisDate)# 21:00:00"> <cfset d2 = "#DatePart('m',thisDate)#/#DatePart('d',thisDate)#/#DatePart('yyyy',thisDate)# 9:00:00"> <cfset d2 = DateAdd("d",1,d2)> <cfoutput>If it's after 10pm</cfoutput> <!--- If it's before 9am ---> <cfelse> <cfset d1 = "#DatePart('m',thisDate)#/#DatePart('d',thisDate)#/#DatePart('yyyy',thisDate)# 21:00:00"> <cfset d1 = DateAdd("d",-1,d1)> <cfset d2 = "#DatePart('m',thisDate)#/#DatePart('d',thisDate)#/#DatePart('yyyy',thisDate)# 9:00:00"> <cfoutput>If it's before 9am</cfoutput> </cfif>

@Dattanand, you won't see the problem when setting "thisDate" to now(). As the OP points out, the issue surfaces when using the DateConvert() function inside of the DateAdd() function. Please see the referenced thread for reproducible examples.

@Michael, In the getDate() function you have used application.GMTOffset, could you please let us know what value you have  set to this variable ? Also let us know the time zone set on the machine.

@Dattanand Application.GMTOffset is "5" to reflect EDT. The timezone on the machine is Pacific (utcHourOffset = 7).

Hi Michael, We tried with the code you had shared in the forum, only difference is I have assigned date1 =CreateODBCDateTime(CreateDateTime(DatePart("yyyy",thisDate),DatePart("m",thisDate),DatePart("d",thisDate),15,12,0) just to repro with the exact time you had specified. I am getting the output as below.   Please let me know if we are missing out something here.   application.GMTOffset set to 5 Code: <cfscript> function getDate() { return DateAdd('h',(application.GMTOffset*-1),DateConvert("local2utc", Now())); } </cfscript> <cfset thisDate = getDate()> <cfset date1 = CreateODBCDateTime(CreateDateTime(DatePart("yyyy",thisDate),DatePart("m",thisDate),DatePart("d",thisDate),15,12,0))> <cfset date2 = CreateODBCDateTime(CreateDateTime(DatePart("yyyy",thisDate),DatePart("m",thisDate),DatePart("d",thisDate),9,0,0))> <cfoutput> date1: #date1#<br /> date2: #date2#<br /> <br /> DateCompare: #DateCompare(date1,date2)#<br /> GTE Evaluation: #date1 GTE date2#<br /> </cfoutput>   Output: date1: \{ts '2018-09-28 15:12:00'} date2: \{ts '2018-09-28 09:00:00'} DateCompare: 1 GTE Evaluation: YES

MIchael, if you could check and confirm, that would be great.

Hi, sorry it took a while to respond. I don't have a lot of free time at the moment. I can confirm that the code you posted evaluates the same as your output. However I fail to see the value in this since what you've posted is different than what I posted. When you run what I posted, like @Eddie Lotter did, do you get the same result as myself and Eddie both did? Cheers, Michael
