compile errors on timezone database

[Olson, Arthur David (NIH/NCI)]

Back in 1998 zic was tweaked to accept 24:00 in "AT" fields; my guess is that the version of zic being used predates that change. (If the vendor hasn't stripped things and you're on a POSIX system, you can do a...
	what /path/to/the/executable/zic
...to get a version number; anything under 7.94 lacks the tweak; anything beyond 7.95 has the tweak.)

Mindful of folks with old compilers, it may be best to change the northamerica file to avoid use of 24:00, changing the "lastSat 24:00" references to "lastSun 0:00". (And perhaps using zic should generate warning messages if a 24:00 shows up and zic's -v option has been
used.)

Subject: compile errors on timezone database


As an fyi, I receive compile errors when I compile (using "zic") the time zone database downloaded in the tzdata2003d.tar file from your ftp://elsie.nci.nih.gov/pub/ site.  The error messages read: "northamerica", line 954: invalid time of day "northamerica", line 955: invalid time of day "northamerica", line 978: invalid time of day "northamerica", line 979: invalid time of day

Those lines in the northamerica file are below.  Is it safe to assume I need to change the 24:00 references to 0:00 instead?  Has anyone else run into this problem?
