ColdFusion UTC时间LTE检查与非UTC时间

Question

我迷路了，我可以检查非UTC时间，并且一切正常。但是，当转换为UTC Times时，CFIF不起作用

非UTC {ts'2019-11-10 14:59:46'} LTE {ts'2019-11-10 14:00:00'}

如果是{ts'2019-11-10 21:59:46'} LTE {ts'2019-11-10 21:00:00'}的UTC

我迷路了……似乎无法弄清楚。

      <cfset timenow = #Now()#>

      <cfset utimenow = dateConvert("Local2UTC", timenow)>

      <cfset admintime = #DateAdd("h", -1, chk.stime)#>
      <cfset uadmintime = #DateAdd("h", -1, chk.utcact)#>

      The chk.stime and chk.utc times are correct. baasically it is taking an hr off time for the cancel window.

      These are the time stamps created.
      NON UTC {ts '2019-11-10 14:59:46'} LTE {ts '2019-11-10 14:00:00'}
      The NonUTC Stamps are time stamps without the UTC Conversions.

      UTC if {ts '2019-11-10 21:59:46'} LTE {ts '2019-11-10 21:00:00'} 

      NonUTC Stamps
      <cfif timenow LTE admintime>
      This one works fine...
       NON UTC {ts '2019-11-10 14:59:46'} LTE {ts '2019-11-10 14:00:00'}
       Then allow cancel
      <cfelse>
      This cfelse is activated properly and Can't Cancel.
       Can't Cancel
      </cfif>

      UTC Stamps
      <cfif utimenow LTE uadmintime>
      This one does not work
       UTC if {ts '2019-11-10 21:59:46'} LTE {ts '2019-11-10 21:00:00'}
       Then allow cancel
       This UTC Time does not activate properly and allows the cancel.
       Executes/Activates inside the cfif - it should not
       <cfelse>
       Can't Cancel
      </cfif>

我也尝试过转换以确保ODBCTime

       <cfset uadmintime = createODBCDateTime(uadmintime)>

Answer 1

ColdFusion可以以各种形式保留日期和时间。 eq，lte等标准比较会根据各种规则比较变量，如果CF使用错误的变量类型进行比较，则会产生意外结果。

我建议总是在比较日期时使用dateCompare() ...

https://cfdocs.org/datecompare

<cfif utimenow LTE uadmintime>
    ...
</cfif>

成为

<cfif dateCompare(utimenow, uadmintime) eq -1>
    ...
</cfif>
