ok, this is an odd one. my red hat 7.3 webserver is acting up. under date and time properties, my time was set to new york EST time zone. on e day all this changed. and the time was set to UTC. when i noticed this and tried to set back to new york EST time, it will not keep the setting, it defaults immediatly back to UTC time. now i can change the time zone to any other zone and it will accept the changes, but when i try to set it back to the new york EST time, it does not accept the change. no error msg, just goes right back to UTC.
when i looked in usr/share/zoneinfo/america at the new_york file, it is empty, and has a file size of )bytes. so i copied a good file from an identical server onto the server im having trouble with, it seemed to accept the change for a minute, then went right back to UTC and the zoneinfo file "new_york" was empty again.
