[erlang-questions] Setting TZ variable

[Ulf Wiger]

Hmm…

At least it works on  my Macbook:

uwiger$ erl
Erlang R14B (erts-5.8.1) [source] [64-bit] [smp:4:4] [rq:4] [async-threads:0] [hipe] [kernel-poll:false]

Eshell V5.8.1  (abort with ^G)
1> os:getenv("TZ").
false
2> time().
{16,42,42}
3> os:putenv("TZ","GMT").
true
4> time().               
{15,43,2}
5> os:putenv("TZ","EST").
true
6> time().               
{10,43,33}


BR,
Ulf W
