I think the CEST comes from Windows. If you don't have TZ set,
I think Cygwin turns the timezone names Windows provides into
abbreviated names by taking the leading letters.
So Windows "Central European Standard Time" => CEST
and "Central European Daylight Time" => CEDT
I've never liked this - arguably Windows is wrong to use non-standard
naming for the timezones. It's even worse for us in the UK - we get
GMTST and GMTDT - ugh. [UK may be a little unusual, but perfectly
reasonable in using GMT and BST.]
You can see the Windows names in registry entry
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones
