How to format UTC revision date

[Lawrence Stewart]

Hi all,

I want to do this:

> hg log -r . --template "{date(date,'%Y%m%d%H%M%S')}\n"
20150503030535

but want to apply the format to the revision's date in UTC rather than
timezone in which the commit was made, and I can't nut out if there's a
way to do it with templates. I found a hacky way which does work:

> date -ur `hg log -r . --template '{date(date, "%s")}\n'` '+%Y%m%d%H%M%S'
20150502170535

The templates-only ideas I tried playing around with failed, I guess
because the inbuilt date() doesn't know how to ingest already formatted
date strings  e.g.:

> hg log -r . --template "{date(utcdate(date),'%Y%m%d%H%M%S')}\n"

Any clue appreciated.
