Using VBA to get system time in GMT equivalent instead of local time

Hello,
I am wondering if there is a simple way to get the GMT equivalent in vba code. I am being a date/timestamp but realized that timezone differences may complicate matters, therefore I would like to "standardize" the timestamps into their GMT equivalent rather then using the computer's local time

I had been using

textbox1.text = Now

and am wondering if there is a simple alteration to this that would acheive what I want it to

thanks in advance
