Mariano, In normal use, offsets can be negative, yes. But in theory, the JDN could be negative as wel, before -4700 ;-) The seconds/nanoseconds are always positive when normalized. That is how I understand it. Sven PS: nanoseconds and even seconds in the offset are a joke, there are no such timezones. On 09 Jun 2012, at 12:28, Mariano Martinez Peck wrote: > Hi guys.

[Pharo-project] What can be negative regarding timezones with date-related objects?

by Mariano Martinez Peck

Hi guys. Imagine in Fuel I am serializing date/time-related objects sending these messages: aDate julianDayNumber. aDateAndTime julianDayNumber. aDateAndTime nanoSecond. aDateAndTime secondsSinceMidnight. aDateAndTime offset asSeconds. aDateAndTime offset nanoSeconds. aDuration asSeconds. aDuration nanoSeconds. aTime asSeconds. aTime nanoeSecond. which of those things could answer negative numbers? because once I remember in my image everything was positive, but in other timezone I think "offset asSeconds" and "offset nanoSeconds" were negative in DateAndTime. thanks! -- Mariano http://marianopeck.wordpress.com

[Pharo-project] recompiling class

by S Krish

Can we do this in Pharo: "in Java, the computation of numeric o ffsets for instance elds in memory is done by the run-time system. This permits updating a class with new instance elds or methods without aff ecting existing code. In other words, it is possible to run an existing bytecode fi le for a subclass after updating and recompiling the class, but without recompiling the subclass."
