[Pharo-project] Synchronizing system time

by Denis Kudriashov

Hello, I try to implement system time synchronization with some server. And I found that when system OS time changed running pharo instance don't see that. I execute DateAndTime>>initializeOffsets but it not helps. Is it bug somewhere? Is it possible to reinitialize OS date and time from running pharo? I use WindowsXP Best regards, Denis

Re: [Pharo-project] PBE2 - PDFs

by StÃ©phane Ducasse

for Zinc it is better to look at the doc of Zinc available on the web site of Zinc because sven prefers to convert from his text to the book later. I'm about to finish to read it and add annotation, then adding also some pictures.
