Developers of Sympa

[Guillaume Rousse <address@concealed>]

The Sympa::Tools::Time module contains a few time-related functions, 
mostly related to conversion between string and timestamps formats:
epoch2yyyymmjj_hhmms()
adate()
get_midnight_time()
epoch_conv()
date_conv()
duration_conv()
parse_date()

Those 300 lines of code would easily be replaced by some perl module 
available from CPAN. Here is a list of potential alternatives:

1) Date::Parse: no dependencies, pure perl, but limited to date string 
conversions (it would not replace duration_conv(), for instance).

2) Date::Manip: few dependencies, pure perl, no idea about the exact 
coverage

3) DateTime framework (DateTime, DateTime::Format::Mail, etc...): 
multiple dependencies, native code, but covers practically everything.

They could be potentially others, but I limited myself to the one known 
to be actively maintained nowadays.

That's basically a choice between a lightweight-but-limited vs 
heavywheight-but-complete external dependency. I'd personaly go for 
DateTime framework, which is basically in line with the "let's get rid 
of old environement constraints", but that's a merely a project 
management decision.
