Hi Python community,
I am trying to convert UTC to PST and want to neglect daylight savings even for
the days that are in PDT, not PST. I simply want every UTC date to be pushed
back by 8 hours and not worry about the days when the difference is really -7
due to daylight savings. I have written a function called utc_to_local (pasted
below) that reads in the UTC year, month, day, and hour from a main code and
returns that value in local standard time. The problem is that I can't figure
out how to "turn off" the automatic daylight savings switch that appears be
built in to somewhere.
Here is some sample output showing the daylight savings switch on April 2, 1995
at 2am local time, which I would like to override.
1995-04-02 08 UTC = 1995-04-02 00 PST
1995-04-02 09 UTC = 1995-04-02 01 PST
1995-04-02 10 UTC = 1995-04-02 03 PDT
1995-04-02 11 UTC = 1995-04-02 04 PDT
I want the third line of the output to read "1995-04-02 02" PST, the fourth to
read "1995-04-02 03", etc.
