How do I display time in gmt when my system clock is set to local
I have my Amateur Radio log in Excel, and likely will be converting it to
Access. My system clock is set to Eastern Time, changing between EST and EDT. I need my entries to display in GMT (Greenwich Mean Time), which is fixed and does not change with DST. |

try this UDF:
Function gmt() As Date Application.Volatile dot = "." Set Serve = GetObject("winmgmts:\\" & dot & "\root\cimv2") Set Zones = Serve.ExecQuery("Select * From Win32_TimeZone") For Each Zone In Zones intTimeZoneBias = Zone.Bias intDayLightBias = Zone.DaylightBias Next gmt = Now() - (intTimeZoneBias - intDayLightBias) / (60 * 24) End Function -- Gary''s Student - gsnu200753 "ai4gk" wrote: I have my Amateur Radio log in Excel, and likely will be converting it to Access.

How do I display time in gmt when my system clock is set to lo
Okay. How do I plug that into the Excel sheet, and will that carry into
Access when I import it? Thanks. "Gary''s Student" wrote: try this UDF: Function gmt() As Date Application.Volatile dot = "."

User Defined Functions (UDFs) are very easy to install and use: 1. ALT-F11 brings up the VBE window 2. ALT-I ALT-M opens a fresh module 3. paste the stuff in and close the VBE window If you save the workbook, the UDF will be saved with it. To remove the UDF: 1. bring up the VBE window as above 2. clear the code out 3. close the VBE window To use this UDF from Excel: =gmt() Like =SUM() or =AVERAGE(), but with no arguments To learn more about macros in general, see: http://www.mvps.org/dmcritchie/excel/getstarted.htm or http://www.cpearson.com/excel/Writin...ionsInVBA.aspx for specifics on UDFs -- Gary''s Student - gsnu200753 "ai4gk" wrote: Okay.
