dateDiff/dateconvert problems when trying to create epoch times

My local server’s timezone is set to UTC-8 – https://www.screencast.com/t/1qqid95lR3v

I need to create epoch time for UTC so I’m trying to use the following function:

#DateDiff(“s”, “January 1 1970 00:00:00”, dateconvert(“local2utc”, now()))#

The dateconvert function does not compute the correct time using any combination.

Here is example code:

<cfset utcTime = dateconvert("local2utc", now())>
<cfoutput>
 now: #now()#
 <br>local2utc: #utcTime#
 <br>epoch (now){currentTime:#DateDiff("s", "January 1 1970 00:00:00", now())#}
 <br/>epoch (local2utc){currentTime:#DateDiff("s", "January 1 1970 00:00:00", dateconvert("local2utc", now()))#}
 <br>epoch (utcTimeVar){currentTime:#DateDiff("s", "January 1 1970 00:00:00", utcTime)#}
</cfoutput>

Here is that code’s output:

now: {ts '2019-04-10 10:54:44'} 
local2utc: {ts '2019-04-10 17:54:44'} 
epoch (now){currentTime:1554890084} 
epoch (local2utc){currentTime:1554890084} 
epoch (utcTimeVar){currentTime:1554890084}

Notice that all 3 epoch times are identical.  The dateconvert value is not being taken into account, even with the utcTimeVar, which is baffling.

Please give me guidance!

Try this and see if it gives you the results your lookings for.

#DateDiff(“s”, “January 1 1970 00:00″, dateTimeFormat(utcTime,”mm-dd-yyyy hh:nn tt”) )#
