Time Conversion Clock

[gavin1f4]

Hey Guys,

 

I am trying to create a clock that shows central time and Zulu time (GMT) as well as having a fill in form where you can enter a time in central and it will convert it to Zulu time. The conversion from central to Zulu time changes from +5 hours during day light savings and +6 when day light savings ends. I wasn't sure how to make this work since daylight savings time changes on different days every year. Here is what I have so far. Thanks for any help.
