Logging of Time Corrections

The clock corrections that are applied using either of GPS-Time or NISTtime programs can be written to a text file as a permanent log. (Or, in the Psion 5 version of NISTtime only, to the clipboard.) This record can be transferred to a Psion spreadsheet which treats the dates and time correctly and will plot the corrections as a graph. If anyone wishes to maintain such a spreadsheet of their own but is unfamiliar with spreadsheet functionality, they are welcome to contact me for a copy in either Psion 3A/3C/3MX or Psion 5 formats.
I don't propose to maintain this graph because I now have a Psion 3mx. The clock on this machine is so accurate that it is within a second or two for month after month.
