Hello Yvan, log "Now surprising behavior. If somebody may explain it, I'm interested."
try
set aString to "12 31/1943"
date aString
log "???? " & result (*???? vendredi 13 mars 2015 12:31:00*)
on error
log "The string doesn't match the current format : " & date string of (current date)
end try
try
set aString to "12 31 1943"
date aString
log "???? " & result (*???? vendredi 13 mars 2015 12:31:00*)
on error
log "The string doesn't match the current format : " & date string of (current date)
end try
On the system used in French, lhe events log is :
(*date vendredi 31 décembre 1943 00:00:00*)
(*date jeudi 31 décembre 2043 00:00:00*)
tell current application
current date
(*The string doesn't match the current format : vendredi 13 mars 2015*)
current date
(*The string doesn't match the current format : vendredi 13 mars 2015*)
(*Now surprising behavior. If somebody may explain it, I'm interested.*)
(*???? vendredi 13 mars 2015 12:31:00*)
(*???? vendredi 13 mars 2015 12:31:00*)
end tell
It will be different on system running in English.
this actually seems to be a compilation issue. If aString is not a date, then the current date is taken (bug or feature?).
It's not what I get. To get a more explicit report I edited a bit the code. Each attempt is now coded as: try set aString to "12 31 1943" date aString log "???? was : " & aString & " > " & result (*???? vendredi 13 mars 2015 12:31:00*) on error log "The string " & aString & " doesn't match the current format : " & date string of (current date) end try
The Events log is (*???? was : 31 12 1943 > vendredi 31 décembre 1943 00:00:00*) (*???? was : 31/12-43 > jeudi 31 décembre 2043 00:00:00*) tell current application current date (*The string 12/31/1943 doesn't match the current format : samedi 14 mars 2015*) current date (*The string 12/31-43 doesn't match the current format : samedi 14 mars 2015*) (*Now surprising behavior. If somebody may explain it, I'm interested.*) (*???? was : 12 31/1943 > samedi 14 mars 2015 12:31:00*) (*???? was : 12 31 1943 > samedi 14 mars 2015 12:31:00*) (*???? was : 12 31 1943 > samedi 14 mars 2015 12:31:00*) current date (*The string 25 34 561943 doesn't match the current format : samedi 14 mars 2015*) end tell
As you may see, "12/31/1943" and "12/31-43" are correctly treated as invalid dates.What is puzzling is that "12 31/1943" and "12 31 1943" are not treated the same way. I don't see any logic behind these different behaviors. Other entries, e.g.
date "25 34 561943" (!)
give an error message on my machine if I try to compile.
