Description
On OSX and maybe other platforms.
The time zone file i.e. /usr/share/zoneinfo/Australia/Sydney is constantly being read (as verified by fs_usage).
It should be cached to prevent unnecessary disk reads. See here for a possible example how:
https://github.com/opdenkamp/xbmc/commit/6801b9f23f5f1430d96ab8d60fd29ce9ca05e365
Note:
See TracTickets
for help on using tickets.
nginx does not read the time zone file by itself. nginx calls libc localtime() function which in turn can read this file. There is no way to prevent libc to read it by nginx means. Please report this issue to Apple.
The example above is Windows-specific interface. Unfortunatly Unicies have no way to get current timezone and daylight state without localtime() functions.
