I have written a Perl script that converts various Tau intervals and Tau times to duration on OE - for example to say how many days minutes are left till 207.54/72:305 or similarly for D0/10:123. However I got stuck at converting OE time such as 2020-12-05T13:45:01 into Tau time. I used Carl Franks libraries on cpan, but could not figure out how to convert OE to GCT.
Can anyone help with that? Thanks
